+# Island → Nextra parity matrix
+
+This matrix is the maintained contract for reproducing the established Island documentation in Nextra. The preserved Island source/build at git revision `86f2008^` and `https://echoui.dev/en/` are the presentation and content references. The current package source and declarations remain authoritative for Echo UI 1.1.x API facts.
+
+## Shell, navigation, and content
+
+| Surface | Island contract | Nextra implementation | Deterministic coverage |
+| --- | --- | --- | --- |
+| Root route | `/` enters the default English documentation without an editorial picker. | The static root permanently redirects to `/en/`. | Route/content inventory and static-export smoke test. |
+| Desktop shell | Fixed 60 px header, 272 px sidebar, 704 px article, right-hand outline. | Island theme tokens and geometry are retained at 1440 × 900. | `island-v1.json` desktop light/dark profiles. |
+| Mobile shell | 56 px header, a separate 48 px section-menu row, off-canvas navigation, single-column content. | `IslandMobileMenu` controls the Nextra mobile navigation with expanded state and focus-visible styling. | `island-v1.json` mobile light/dark profiles at 390 × 844. |
+| Locales and themes | English and Chinese share the route hierarchy; light and dark retain the same geometry. | Every representative baseline route is exercised in `en`/`zh`, light/dark, desktop/mobile. | 16 locale/profile/category combinations per category in `verify-docs-ui.mjs`. |
+| Header links | Links contains GitHub, Discord, and Twitter. | The exact three Island destinations are restored. | Content inventory plus interactive UI verification. |
+| Guide sidebar | A `Guide` section contains Introduction, Installation, and Declaration; `About` is separated. | Locale-specific Nextra metadata uses Guide/About separators. | Content inventory and rendered sidebar assertions. |
+| Page affordances | Edit link, last-updated metadata, previous/next navigation, and footer are visible. | Nextra edit/navigation defaults are restored; the footer contains the MIT license and copyright. | Static output and UI assertions. |
+| External prose links | Brand-colored Island link treatment without an appended arrow glyph. | Nextra's external-link icon is hidden in article prose while external semantics remain intact. | Visual baseline assertion. |
+| Callouts | Neutral bordered panel without blue info chrome. | Nextra callouts use the Island background, border, color, spacing, and no decorative icon. | Guide baseline assertion. |
+| Introduction | Five compact feature bullets under one Features heading. | Updated factual copy retains the five-item list rhythm and avoids five H3 sections. | Bilingual content inventory. |
+| Installation | A four-step installation story. | Requirements/compatibility, package installation, Tailwind configuration, then import/render form the four primary steps. | Bilingual content inventory; Tailwind compatibility verifier. |
+| About | Project contacts plus Discord and WeChat community choices. | The shipped `/wechat.jpg` QR image and WeChat option are restored in both locales. | Bilingual content inventory and asset smoke test. |
+| Declaration | Copy promises the edit affordance that the shell actually provides. | The page-level edit link is enabled and the bilingual declaration copy agrees. | Bilingual content inventory and rendered edit-link check. |
+
+## Component examples
+
+Every entry below is a live rendered preview with an adjacent Preview/Code tab and copy action. There are no intentionally omitted Island variants.
+
+| Component | Required live variants | Count |
+| --- | --- | --: |
+| Button | Default; Toggle State; Disabled State; Size; Rounded Corners; Button Group | 6 |
+| Checkbox | Default; Disabled State; Size; Color; Checkbox Group | 5 |
+| Envelope | ADSR Envelope; AHDSR Envelope; Delay/DADSR | 3 |
+| Input | Default; Disabled State; Bilateral Mode; Text Mode; Size; Rounded Corners; Progress Bar Color; Minimum and Maximum Values; Step and Sensitivity | 9 |
+| Knob | Default; Disabled; Bilateral Rotation Mode; Rotation Angle Range; Labels; Step and Sensitivity; Size-Related; Color-Related; Knob Group | 9 |
+| Radio | Default; Disabled State; Size; Color; Radio Group | 5 |
+| Slider | Default; Disabled State; Vertical Mode; Bilateral Mode; Adding Coordinates; Step; Custom Styling; Uncontrolled Mode | 8 |
+| Switch | Default; Toggled State; Disabled State; Size; Custom Styling | 5 |
+| LFO | Default; Delay | 2 |
+| Light | Default; On State; Light Color; Size | 4 |
+| Oscilloscope | Default | 1 |
+| Spectrogram | Audio Data; Axis; Grid; Use Case: EQ3 | 4 |
+| VU Meter | Default; Horizontal Mode; Stereo Mode; Compact Mode; Number of Volume Bars; Custom Colors | 6 |
+| Waveform | Default | 1 |
+| Card | Default; Active State; Real-World Scenario | 3 |
+
+The 71-variant inventory lives in one bilingual data model so labels, source, counts, and rendered examples cannot silently drift between locales. Preview/Code uses an ARIA tablist, supports arrow, Home, and End keys, keeps the active tab in the tab order, and exposes copy success/failure through a polite status. Reduced motion removes transitions. The richer Nextra real-audio/status demonstrations remain above the variant matrix and supplement it.
+
+## API, public types, and data attributes
+
+| Surface | Parity contract | Maintained behavior |
+| --- | --- | --- |
+| API hierarchy | Component/compound-component headings precede visible tables. | Generated tables remain because they cover the current public declarations. |
+| Column order | Attribute / Description / Type / Default. | Both locales render that Island order; translated labels preserve the same order. |
+| Public types | Inherited React attributes, compound APIs, callback payloads, exported data shapes, and limitations remain discoverable. | Generated rows plus the inherited-contract paragraph are sourced from the current package types. |
+| Controller data attributes | Button, Checkbox, Input, Knob, Radio, Slider, and Switch attributes are listed. | Values and meanings are rendered beside each API. |
+| Display data tags | VU Meter segment `data-active` bands and Card `data-toggled` are listed. | Values are based on the current runtime. |
+
+The current Button runtime emits `data-disable`, not the legacy page's `data-disabled`. The docs show the actual runtime spelling because package behavior is the frozen source of truth; changing the shipped runtime solely for documentation parity is out of scope.
+
+## Intentional modernized exceptions
+
+- Nextra and static export remain the documentation toolchain. IslandJS, NextUI, `react-live`, and stale implementation dependencies are not restored.
+- Echo UI 1.1.x compatibility remains accurate: React 18.2–19, Tailwind CSS 3/4, tailwind-variants 3.2.x, tailwind-merge 3.6.x, and Tone.js 15.1.22.
+- Accessibility guidance, native fallback controls, focus-visible treatment, keyboard-operable source disclosure, reduced-motion behavior, lifecycle cleanup, and error recovery remain.
+- Real Web Audio demonstrations, status text, reconnect flows, and restart-safe audio graphs remain and supplement the Island variant examples.
+- Generated API tables replace copied declaration blocks where the complete current public contract is already visible.
+- Nextra's search implementation, locale switch, theme switch, static route format, and last-updated source remain, styled to the Island hierarchy.
+
+No other parity exception is approved by this matrix.

+# CI repair handoff 1
+
+- Run ID: `20260724T132107Z-issue-108-743034`
+- Draft PR: https://github.com/codeacme17/echo-ui/pull/111
+- Failed workflow run: https://github.com/codeacme17/echo-ui/actions/runs/30122020412
+- Reviewed candidate head: `8ddb38818164f6b0b0d77b236c0dd3fb6cf2a626`
+- Frozen base: `9eea05360a90e46a4c66c2e821e9ad5bd6c71c67`
+- Prior implementation commit: `b15cded4fb9fa319bb35e56a70a4401cbf1d0e33`
+
+## Failure classification
+
+The low-privilege evidence workflow failed before candidate tests:
+
+1. `validate-candidate-control-plane.mjs` rejected changes to the protected
+ verification plane:
+ - `scripts/capture-docs-evidence.mjs`
+ - `scripts/create-docs-redirects.mjs`
+ - `scripts/verify-docs-ui.mjs`
+ - `scripts/verify-nextra-output.mjs`
+2. `generate-evidence.mjs` rejected the screenshot metadata because every
+ `(scenario, route, viewport)` tuple must contain both a `before` and an `after`
+ phase.
+
+These are accepted CI findings. They do not authorize weakening the frozen issue
+acceptance criteria or modifying the loop/control/workflow/package plane.
+
+## Required repair
+
+1. Restore every file under root `scripts/` to the frozen-base version. The final
+ exact-head diff must contain no root `scripts/` changes.
+2. Preserve the equivalent deterministic Island comparison in allowed product/test
+ paths such as `tests/`, `docs/visual-baselines/`, and documentation components.
+ `pnpm verify` must continue to execute the maintained contract through the
+ existing test command without changing package manifests or verification config.
+3. Preserve root `/` → `/en/` behavior without modifying
+ `scripts/create-docs-redirects.mjs`. Use an allowed documentation application
+ implementation and add allowed tests that prove both runtime and exported
+ behavior available from the unchanged build pipeline.
+4. Reorganize committed screenshots under:
+ - `screen-shots/20260724T132107Z-issue-108-743034/before/`
+ - `screen-shots/20260724T132107Z-issue-108-743034/after/`
+5. Add or update the screenshot metadata consumed by the existing evidence
+ generator. Every entry must contain `name`, `scenario`, `route`, `viewport`,
+ `phase`, `capturedAt`, and the correct `sourceSha`. Every scenario/route/viewport
+ key must have one meaningful frozen-base before image and one exact
+ implementation after image. Do not treat historical migration previews as
+ acceptance pairs.
+6. Keep the PR Draft. Do not push, update/create a PR, mark Ready, approve, or
+ merge.
+
+## Required checks
+
+- Targeted tests for the parity contract, example frame, route inventory, root
+ redirect, and screenshot metadata.
+- `pnpm lint`
+- `pnpm typecheck:docs`
+- `pnpm build:docs`
+- `pnpm test:docs`
+- `pnpm verify`
+- After the repair commit exists, run the trusted candidate-control validator
+ against frozen base and the new exact HEAD; it must report no protected paths.
+
+## Result contract
+
+Commit the repair locally as a descendant of the current branch. Write, but do not
+commit,
+`loops/issue-dev-loop/logs/runs/20260724T132107Z-issue-108-743034/implementation-result-2.json`

+# Implementation brief
+
+- Run ID: `20260724T132107Z-issue-108-743034`
+- Issue: #108 — docs: close the remaining Island UI and content parity gaps in Nextra
+- Issue URL: https://github.com/codeacme17/echo-ui/issues/108
+- Base branch: `dev`
+- Base SHA: `9eea05360a90e46a4c66c2e821e9ad5bd6c71c67`
+- Branch: `codex/issue-108`
+- UI evidence required: yes
+
+## Issue snapshot
+
+## Context
+
+This is a follow-up to #97 / #98. That work required the Nextra documentation to reproduce the established Island site exactly, with `https://echoui.dev/en/` as the visual source of truth. A fresh comparison against the current `dev` branch shows that the shell is closer, but substantial UI, information-architecture, and example-coverage differences remain.
+
+Keep Nextra. “Parity” here means preserving the Island presentation and documentation coverage while retaining factual improvements made for Echo UI 1.1.x (React 19, Tailwind CSS 4, Tone.js 15, accessibility, lifecycle, and error guidance). It does **not** mean restoring IslandJS, NextUI, stale setup instructions, or old implementation dependencies.
+
+## How to compare
+
+1. Run `pnpm dev:docs`.
+2. Compare the same English and Chinese routes against `https://echoui.dev/en/` and `https://echoui.dev/zh/`.
+3. At minimum, inspect `/`, `/guide/introduction`, `/guide/about`, `/component/button`, `/component/knob`, `/component/spectrogram`, and `/hook/usePlayer`.
+4. Compare 1440×900 and 390×844 in both light and dark themes.
+
+## Observed differences
+
+### 1. Site shell and navigation
+
+| Area | Island reference | Current Nextra site |
+| --- | --- | --- |
+| `/` | Redirects directly to `/en` | Shows a separate editorial “Choose your documentation language” landing page |
+| Links menu | GitHub, Discord, Twitter | Discussions, Issues, Discord |
+| Guide sidebar | Shows a `Guide` group heading and a separated `About` group | Renders a flat four-link list |
+| Contribution/navigation affordances | Exposes “Edit this page on GitHub”, last-updated metadata, and previous/next page navigation | `editLink={null}` and `navigation={false}`; only the timestamp remains |
+| Footer | Island configuration contains license/copyright and page navigation metadata | The Nextra footer is mounted but globally hidden |
+| External links | Plain Island link treatment | Nextra adds external-link arrow glyphs throughout prose |
+| Callouts | Neutral Island bordered panel | Blue Nextra info callout with icon and different spacing/color |
+
+There is also a content/implementation contradiction: the Declaration page says readers can use “the edit link on each page”, while the layout explicitly disables edit links.
+
+Relevant files:
+
+- `docs/app/[lang]/layout.tsx`
+- `docs/app/[lang]/island-theme.css`
+- `docs/app/(landing)/page.tsx`
+- `docs/content/en/_meta.ts`
+- `docs/content/zh/_meta.ts`
+- `docs/content/*/guide/declaration.mdx`
+
+### 2. Guide content and hierarchy
+
+- Introduction feature bullets became five H3 sections. This materially changes page length, scan rhythm, and the table of contents.
+- All guide copy was rewritten rather than migrated in place. Some updates are useful and should remain, but the result is not content parity with the Island reference.
+- About removed the WeChat community option and QR code even though `wechat.jpg` is still shipped as a public asset.
+- Installation is correctly modernized for 1.1.x, but its presentation no longer follows the four-step Island structure.
+- The root language-selection page introduces a visual language that does not exist anywhere in the Island site.
+
+### 3. Component example coverage was reduced
+
+The Island source had 30 files under `docs/src/components/UsageBox` and `docs/src/components/Example`. The current site consolidates the documentation into a small set of shared demo files and generally renders one demo per component page.
+
+| Component | Island examples no longer shown as equivalent live variants |
+| --- | --- |
+| Button | default, toggled, disabled, sizes, radii, group |
+| Checkbox | default, disabled, sizes, colors, group |
+| Envelope | ADSR, AHDSR, DADSR/delay |
+| Input | default, disabled, bilateral, text, sizes, radii, progress color, min/max, step/sensitivity |
+| Knob | default, disabled, bilateral, rotation range, labels, step/sensitivity, sizes, colors, group |
+| Radio | default, disabled, sizes, colors, group |
+| Slider | default, disabled, vertical, bilateral, axis, step, custom styling, uncontrolled |
+| Switch | default, toggled, disabled, sizes, custom styling |
+| LFO | default and delay |
+| Light | default, on, colors, sizes |
+| Spectrogram | default, axis, grid, EQ3 scenario |
+| VU Meter | default, horizontal, stereo, compact, segment count, custom colors |
+| Card | default, active, real-world scenario |
+
+Oscilloscope and Waveform still have a live example, but they also lost the Island example affordance described below.
+
+### 4. The example and API presentation is different
+
+- Island gives every example a `Preview` / `Code` switch. The current demo frame has only a `Preview` label; source is no longer available beside each rendered variant.
+- Current demos add useful live status and more realistic audio flows, but they replace rather than supplement the variant matrix above.
+- Island API tables use `Attribute / Description / Type / Default`; current tables use `Prop / Type / Default / Description` and add a new inherited-props paragraph.
+- Dedicated Data Attributes/Data Tags sections were removed from most component pages. The current docs only surface a small subset (for example VU Meter `data-active` and Card `data-toggled`).
+- Full type-declaration blocks were removed in favor of generated API tables. Keep the tables if they are complete, but restore any public contract details that are no longer discoverable.
+- Hook pages gained live demos, lifecycle, and error guidance; preserve those improvements while matching the Island visual hierarchy and API discoverability.
+
+Relevant files:
+
+- `docs/app/_components/controller-demo.tsx`
+- `docs/app/_components/display-*.tsx`
+- `docs/app/_components/hook-demo.tsx`
+- `docs/app/_components/*-api.tsx`
+- `docs/app/_components/*-docs.module.css`
+- `docs/content/{en,zh}/component/*.mdx`
+- `docs/content/{en,zh}/hook/*.mdx`
+
+## Why the current regression check misses this
+
+`scripts/verify-docs-ui.mjs` compares the current site with hand-written style constants. It does not compare the output with an Island screenshot/DOM baseline. It verifies the shell mainly through the Button route and only requires each component route to contain at least one demo, so it cannot catch reduced example coverage, changed copy/hierarchy, missing links, or changed root behavior.
+
+The two files under `docs/screenshots/` are unreferenced migration-preview captures, not Island parity baselines.
+
+## Acceptance criteria
+
+- [ ] Create and document an Island → Nextra parity matrix covering shell, navigation, content hierarchy, examples, API/data-attribute coverage, and intentional modernized exceptions.
+- [ ] Match the Island shell at 1440×900 and 390×844 in English/Chinese and light/dark themes, including the root-route behavior, sidebar grouping, callouts, link treatment, and page-level navigation affordances.
+- [ ] Restore the Island Links destinations, edit-page affordance, previous/next navigation, and footer behavior, or explicitly document an approved product decision for each deviation.
+- [ ] Fix the Declaration copy so it agrees with the actual edit-link behavior.
+- [ ] Give every Island component variant an equivalent live preview and adjacent copyable source, unless its removal is explicitly approved in the parity matrix.
+- [ ] Restore missing Data Attributes/Data Tags and public type/API details.
+- [ ] Preserve the current 1.1.x installation, Tone.js 15, accessibility, lifecycle, error-handling, and real-audio-demo improvements.
+- [ ] Replace the current style-constant-only check with maintained Island visual baselines (or an equivalent deterministic comparison) for representative guide, controller, visualization, Hook, and home routes.
+- [ ] Add content-inventory assertions for example labels/counts, Links destinations, edit/pagination controls, root behavior, and both locales.
+- [ ] `pnpm lint`, `pnpm typecheck:docs`, `pnpm build:docs`, and `pnpm test:docs` pass.
+
+## Out of scope
+
+- Reintroducing IslandJS, NextUI, or `react-live`
+- Reverting accurate Echo UI 1.1.x compatibility and API information
+- Removing accessibility or real Web Audio improvements solely to obtain pixel parity
+
+
+## Frozen implementation contract
+
+### Acceptance criteria
+
+1. Add a maintained Island → Nextra parity matrix that covers:
+ - root-route behavior;
+ - desktop and mobile shell/navigation;
+ - both locales and both color schemes;
+ - guide hierarchy and content exceptions;
+ - component example labels/counts;
+ - Preview/Code behavior;
+ - API, public type, and data-attribute coverage;
+ - every intentional modernized exception.
+2. Make `/` follow the Island language-routing behavior instead of presenting a
+ separate editorial language picker.
+3. Match the Island shell on the required representative routes at 1440×900 and
+ 390×844 in English and Chinese, light and dark:
+ - preserve the Island header and mobile-menu hierarchy;
+ - restore the Links destinations (GitHub, Discord, Twitter);
+ - restore Guide/About sidebar grouping;
+ - restore edit-page, last-updated, previous/next, and visible footer behavior;
+ - use Island-like external-link and callout treatments.
+4. Reconcile Declaration copy with the restored edit-page affordance.
+5. Restore the Island guide hierarchy and essential content, including the
+ Introduction feature list rhythm and the About WeChat option/QR image, while
+ retaining accurate Echo UI 1.1.x installation and compatibility guidance.
+6. Give every component variant listed in the issue snapshot an equivalent live
+ preview and adjacent copyable source. A deliberately omitted variant must be
+ named and justified in the parity matrix.
+7. Preserve the richer real-audio, status, accessibility, lifecycle, and error
+ handling added by the Nextra migration; these supplement rather than replace
+ the Island variant matrix.
+8. Restore discoverable Data Attributes/Data Tags and public API/type details.
+ Generated tables may remain when complete, but their visible column order and
+ hierarchy must follow the Island contract where parity is expected.
+9. Replace the style-constant-only regression coverage with deterministic,
+ maintained Island visual baselines (or an equivalent deterministic screenshot
+ comparison) for home, guide, controller, visualization, and Hook categories.
+10. Add content-inventory assertions for both locales covering example
+ labels/counts, Links destinations, root behavior, edit/pagination/footer
+ controls, guide grouping, and representative API/data-attribute details.
+11. `pnpm lint`, `pnpm typecheck:docs`, `pnpm build:docs`, `pnpm test:docs`, and
+ the full `pnpm verify` pass.
+
+### In scope
+
+- `docs/app/**`, `docs/content/{en,zh}/**`, and documentation-only styles/assets.
+- Shared documentation demo/source/API components.
+- Documentation route, content-inventory, and visual-parity verification scripts
+ and tests.
+- Documentation of the parity matrix and intentionally retained modern behavior.
+- Test fixtures/baselines that are deterministic and checked into the repository.
+
+### Out of scope
+
+- Reintroducing IslandJS, NextUI, or `react-live`.
+- Reverting React 19, Tailwind CSS 4, Tone.js 15, accessibility, lifecycle,
+ error-handling, or real Web Audio improvements.
+- Changing the shipped Echo UI component/hook runtime or public package API solely
+ to make the documentation resemble the legacy site.
+- New production dependencies, release/version changes, or unrelated refactors.
+
+### Pre-agreed TDD seams
+
+1. First make content-inventory tests fail for root behavior, navigation links,
+ Guide/About grouping, footer/edit/pagination controls, both locales, variant
+ labels/counts, source affordances, and representative data attributes/API rows.
+2. Add or revise deterministic visual-parity assertions so they fail against the
+ current Nextra shell before changing shell styles or structure.
+3. Implement the smallest shared demo/source model that can express all required
+ variants, adding targeted tests for each controller/display category before
+ populating page content.
+4. Keep modern audio-demo behavior covered while extending Preview/Code; source
+ disclosure and copy controls must be keyboard-accessible.
+5. Run the closest targeted Vitest/Node check after each seam and
+ `pnpm typecheck:docs` regularly.
+
+### Required targeted checks
+
+- Targeted Vitest tests for docs route/content inventory.
+- Targeted Node checks for Nextra output and visual-parity baselines.
+- `pnpm lint`
+- `pnpm typecheck:docs`
+- `pnpm build:docs`
+- `pnpm test:docs`
+- `pnpm verify` as the final implementation check.
+
+### Required UI evidence
+
+Store before/after evidence under
+`screen-shots/20260724T132107Z-issue-108-743034/` with an index that maps each
+capture to its route, locale, theme, viewport, and acceptance criterion.
+
+- Viewports: 1440×900 and 390×844.
+- Locales/themes: English and Chinese, light and dark.
+- Routes: home, `/guide/introduction`, `/guide/about`, `/component/button`,
+ `/component/knob`, `/component/spectrogram`, and `/hook/usePlayer`.
+- Interaction evidence: desktop Links menu, mobile navigation, locale/theme
+ switching, previous/next navigation, edit link, Preview/Code switching, source
+ copy action, and at least one real-audio demo state.
+- Include focused before/after comparisons for representative home, guide,
+ controller, visualization, and Hook pages. The evidence index may use a
+ documented representative matrix instead of duplicating every unchanged
+ combination, but all locale/theme/viewport combinations must be exercised by a
+ deterministic check.
+- Record keyboard/focus and reduced-motion observations for new interactive UI.
+
+### Risks and owner-confirmation boundaries
+
+- The owner has explicitly approved the issue's >400-line implementation budget.
+- Stop for owner confirmation before adding a dependency, changing a shipped
+ package API/runtime, changing release metadata, weakening accessibility or
+ security behavior, or approving an intentional parity exception not already
+ stated above.
+- Treat the live Island site as the visual/content reference and the current
+ package implementation/types as the source of truth for modern API facts.
+- Prefer shared data-driven documentation structures over duplicating large
+ locale-specific React implementations.
+
+### Stop conditions
+
+- A requirement conflicts with the current public runtime/API and cannot be
+ resolved as documentation-only work.
+- A required Island reference/baseline cannot be captured deterministically.
+- An in-scope check fails twice for causes outside the issue's changes.
+- Work would require a new dependency, release change, security-sensitive change,
+ or product/API decision.
+- The implementation is complete and committed.
+
+Stop after committing. Do not push, create a PR, or merge.

+ "briefSource": "# Implementation brief\n\n- Run ID: `20260724T132107Z-issue-108-743034`\n- Issue: #108 — docs: close the remaining Island UI and content parity gaps in Nextra\n- Issue URL: https://github.com/codeacme17/echo-ui/issues/108\n- Base branch: `dev`\n- Base SHA: `9eea05360a90e46a4c66c2e821e9ad5bd6c71c67`\n- Branch: `codex/issue-108`\n- UI evidence required: yes\n\n## Issue snapshot\n\n## Context\n\nThis is a follow-up to #97 / #98. That work required the Nextra documentation to reproduce the established Island site exactly, with `https://echoui.dev/en/` as the visual source of truth. A fresh comparison against the current `dev` branch shows that the shell is closer, but substantial UI, information-architecture, and example-coverage differences remain.\n\nKeep Nextra. “Parity” here means preserving the Island presentation and documentation coverage while retaining factual improvements made for Echo UI 1.1.x (React 19, Tailwind CSS 4, Tone.js 15, accessibility, lifecycle, and error guidance). It does **not** mean restoring IslandJS, NextUI, stale setup instructions, or old implementation dependencies.\n\n## How to compare\n\n1. Run `pnpm dev:docs`.\n2. Compare the same English and Chinese routes against `https://echoui.dev/en/` and `https://echoui.dev/zh/`.\n3. At minimum, inspect `/`, `/guide/introduction`, `/guide/about`, `/component/button`, `/component/knob`, `/component/spectrogram`, and `/hook/usePlayer`.\n4. Compare 1440×900 and 390×844 in both light and dark themes.\n\n## Observed differences\n\n### 1. Site shell and navigation\n\n| Area | Island reference | Current Nextra site |\n| --- | --- | --- |\n| `/` | Redirects directly to `/en` | Shows a separate editorial “Choose your documentation language” landing page |\n| Links menu | GitHub, Discord, Twitter | Discussions, Issues, Discord |\n| Guide sidebar | Shows a `Guide` group heading and a separated `About` group | Renders a flat four-link list |\n| Contribution/navigation affordances | Exposes “Edit this page on GitHub”, last-updated metadata, and previous/next page navigation | `editLink={null}` and `navigation={false}`; only the timestamp remains |\n| Footer | Island configuration contains license/copyright and page navigation metadata | The Nextra footer is mounted but globally hidden |\n| External links | Plain Island link treatment | Nextra adds external-link arrow glyphs throughout prose |\n| Callouts | Neutral Island bordered panel | Blue Nextra info callout with icon and different spacing/color |\n\nThere is also a content/implementation contradiction: the Declaration page says readers can use “the edit link on each page”, while the layout explicitly disables edit links.\n\nRelevant files:\n\n- `docs/app/[lang]/layout.tsx`\n- `docs/app/[lang]/island-theme.css`\n- `docs/app/(landing)/page.tsx`\n- `docs/content/en/_meta.ts`\n- `docs/content/zh/_meta.ts`\n- `docs/content/*/guide/declaration.mdx`\n\n### 2. Guide content and hierarchy\n\n- Introduction feature bullets became five H3 sections. This materially changes page length, scan rhythm, and the table of contents.\n- All guide copy was rewritten rather than migrated in place. Some updates are useful and should remain, but the result is not content parity with the Island reference.\n- About removed the WeChat community option and QR code even though `wechat.jpg` is still shipped as a public asset.\n- Installation is correctly modernized for 1.1.x, but its presentation no longer follows the four-step Island structure.\n- The root language-selection page introduces a visual language that does not exist anywhere in the Island site.\n\n### 3. Component example coverage was reduced\n\nThe Island source had 30 files under `docs/src/components/UsageBox` and `docs/src/components/Example`. The current site consolidates the documentation into a small set of shared demo files and generally renders one demo per component page.\n\n| Component | Island examples no longer shown as equivalent live variants |\n| --- | --- |\n| Button | default, toggled, disabled, sizes, radii, group |\n| Checkbox | default, disabled, sizes, colors, group |\n| Envelope | ADSR, AHDSR, DADSR/delay |\n| Input | default, disabled, bilateral, text, sizes, radii, progress color, min/max, step/sensitivity |\n| Knob | default, disabled, bilateral, rotation range, labels, step/sensitivity, sizes, colors, group |\n| Radio | default, disabled, sizes, colors, group |\n| Slider | default, disabled, vertical, bilateral, axis, step, custom styling, uncontrolled |\n| Switch | default, toggled, disabled, sizes, custom styling |\n| LFO | default and delay |\n| Light | default, on, colors, sizes |\n| Spectrogram | default, axis, grid, EQ3 scenario |\n| VU Meter | default, horizontal, stereo, compact, segment count, custom colors |\n| Card | default, active, real-world scenario |\n\nOscilloscope and Waveform still have a live example, but they also lost the Island example affordance described below.\n\n### 4. The example and API presentation is different\n\n- Island gives every example a `Preview` / `Code` switch. The current demo frame has only a `Preview` label; source is no longer available beside each rendered variant.\n- Current demos add useful live status and more realistic audio flows, but they replace rather than supplement the variant matrix above.\n- Island API tables use `Attribute / Description / Type / Default`; current tables use `Prop / Type / Default / Description` and add a new inherited-props paragraph.\n- Dedicated Data Attributes/Data Tags sections were removed from most component pages. The current docs only surface a small subset (for example VU Meter `data-active` and Card `data-toggled`).\n- Full type-declaration blocks were removed in favor of generated API tables. Keep the tables if they are complete, but restore any public contract details that are no longer discoverable.\n- Hook pages gained live demos, lifecycle, and error guidance; preserve those improvements while matching the Island visual hierarchy and API discoverability.\n\nRelevant files:\n\n- `docs/app/_components/controller-demo.tsx`\n- `docs/app/_components/display-*.tsx`\n- `docs/app/_components/hook-demo.tsx`\n- `docs/app/_components/*-api.tsx`\n- `docs/app/_components/*-docs.module.css`\n- `docs/content/{en,zh}/component/*.mdx`\n- `docs/content/{en,zh}/hook/*.mdx`\n\n## Why the current regression check misses this\n\n`scripts/verify-docs-ui.mjs` compares the current site with hand-written style constants. It does not compare the output with an Island screenshot/DOM baseline. It verifies the shell mainly through the Button route and only requires each component route to contain at least one demo, so it cannot catch reduced example coverage, changed copy/hierarchy, missing links, or changed root behavior.\n\nThe two files under `docs/screenshots/` are unreferenced migration-preview captures, not Island parity baselines.\n\n## Acceptance criteria\n\n- [ ] Create and document an Island → Nextra parity matrix covering shell, navigation, content hierarchy, examples, API/data-attribute coverage, and intentional modernized exceptions.\n- [ ] Match the Island shell at 1440×900 and 390×844 in English/Chinese and light/dark themes, including the root-route behavior, sidebar grouping, callouts, link treatment, and page-level navigation affordances.\n- [ ] Restore the Island Links destinations, edit-page affordance, previous/next navigation, and footer behavior, or explicitly document an approved product decision for each deviation.\n- [ ] Fix the Declaration copy so it agrees with the actual edit-link behavior.\n- [ ] Give every Island component variant an equivalent live preview and adjacent copyable source, unless its removal is explicitly approved in the parity matrix.\n- [ ] Restore missing Data Attributes/Data Tags and public type/API details.\n- [ ] Preserve the current 1.1.x installation, Tone.js 15, accessibility, lifecycle, error-handling, and real-audio-demo improvements.\n- [ ] Replace the current style-constant-only check with maintained Island visual baselines (or an equivalent deterministic comparison) for representative guide, controller, visualization, Hook, and home routes.\n- [ ] Add content-inventory assertions for example labels/counts, Links destinations, edit/pagination controls, root behavior, and both locales.\n- [ ] `pnpm lint`, `pnpm typecheck:docs`, `pnpm build:docs`, and `pnpm test:docs` pass.\n\n## Out of scope\n\n- Reintroducing IslandJS, NextUI, or `react-live`\n- Reverting accurate Echo UI 1.1.x compatibility and API information\n- Removing accessibility or real Web Audio improvements solely to obtain pixel parity\n\n\n## Frozen implementation contract\n\n### Acceptance criteria\n\n1. Add a maintained Island → Nextra parity matrix that covers:\n - root-route behavior;\n - desktop and mobile shell/navigation;\n - both locales and both color schemes;\n - guide hierarchy and content exceptions;\n - component example labels/counts;\n - Preview/Code behavior;\n - API, public type, and data-attribute coverage;\n - every intentional modernized exception.\n2. Make `/` follow the Island language-routing behavior instead of presenting a\n separate editorial language picker.\n3. Match the Island shell on the required representative routes at 1440×900 and\n 390×844 in English and Chinese, light and dark:\n - preserve the Island header and mobile-menu hierarchy;\n - restore the Links destinations (GitHub, Discord, Twitter);\n - restore Guide/About sidebar grouping;\n - restore edit-page, last-updated, previous/next, and visible footer behavior;\n - use Island-like external-link and callout treatments.\n4. Reconcile Declaration copy with the restored edit-page affordance.\n5. Restore the Island guide hierarchy and essential content, including the\n Introduction feature list rhythm and the About WeChat option/QR image, while\n retaining accurate Echo UI 1.1.x installation and compatibility guidance.\n6. Give every component variant listed in the issue snapshot an equivalent live\n preview and adjacent copyable source. A deliberately omitted variant must be\n named and justified in the parity matrix.\n7. Preserve the richer real-audio, status, accessibility, lifecycle, and error\n handling added by the Nextra migration; these supplement rather than replace\n the Island variant matrix.\n8. Restore discoverable Data Attributes/Data Tags and public API/type details.\n Generated tables may remain when complete, but their visible column order and\n hierarchy must follow the Island contract where parity is expected.\n9. Replace the style-constant-only regression coverage with deterministic,\n maintained Island visual baselines (or an equivalent deterministic screenshot\n comparison) for home, guide, controller, visualization, and Hook categories.\n10. Add content-inventory assertions for both locales covering example\n labels/counts, Links destinations, root behavior, edit/pagination/footer\n controls, guide grouping, and representative API/data-attribute details.\n11. `pnpm lint`, `pnpm typecheck:docs`, `pnpm build:docs`, `pnpm test:docs`, and\n the full `pnpm verify` pass.\n\n### In scope\n\n- `docs/app/**`, `docs/content/{en,zh}/**`, and documentation-only styles/assets.\n- Shared documentation demo/source/API components.\n- Documentation route, content-inventory, and visual-parity verification scripts\n and tests.\n- Documentation of the parity matrix and intentionally retained modern behavior.\n- Test fixtures/baselines that are deterministic and checked into the repository.\n\n### Out of scope\n\n- Reintroducing IslandJS, NextUI, or `react-live`.\n- Reverting React 19, Tailwind CSS 4, Tone.js 15, accessibility, lifecycle,\n error-handling, or real Web Audio improvements.\n- Changing the shipped Echo UI component/hook runtime or public package API solely\n to make the documentation resemble the legacy site.\n- New production dependencies, release/version changes, or unrelated refactors.\n\n### Pre-agreed TDD seams\n\n1. First make content-inventory tests fail for root behavior, navigation links,\n Guide/About grouping, footer/edit/pagination controls, both locales, variant\n labels/counts, source affordances, and representative data attributes/API rows.\n2. Add or revise deterministic visual-parity assertions so they fail against the\n current Nextra shell before changing shell styles or structure.\n3. Implement the smallest shared demo/source model that can express all required\n variants, adding targeted tests for each controller/display category before\n populating page content.\n4. Keep modern audio-demo behavior covered while extending Preview/Code; source\n disclosure and copy controls must be keyboard-accessible.\n5. Run the closest targeted Vitest/Node check after each seam and\n `pnpm typecheck:docs` regularly.\n\n### Required targeted checks\n\n- Targeted Vitest tests for docs route/content inventory.\n- Targeted Node checks for Nextra output and visual-parity baselines.\n- `pnpm lint`\n- `pnpm typecheck:docs`\n- `pnpm build:docs`\n- `pnpm test:docs`\n- `pnpm verify` as the final implementation check.\n\n### Required UI evidence\n\nStore before/after evidence under\n`screen-shots/20260724T132107Z-issue-108-743034/` with an index that maps each\ncapture to its route, locale, theme, viewport, and acceptance criterion.\n\n- Viewports: 1440×900 and 390×844.\n- Locales/themes: English and Chinese, light and dark.\n- Routes: home, `/guide/introduction`, `/guide/about`, `/component/button`,\n `/component/knob`, `/component/spectrogram`, and `/hook/usePlayer`.\n- Interaction evidence: desktop Links menu, mobile navigation, locale/theme\n switching, previous/next navigation, edit link, Preview/Code switching, source\n copy action, and at least one real-audio demo state.\n- Include focused before/after comparisons for representative home, guide,\n controller, visualization, and Hook pages. The evidence index may use a\n documented representative matrix instead of duplicating every unchanged\n combination, but all locale/theme/viewport combinations must be exercised by a\n deterministic check.\n- Record keyboard/focus and reduced-motion observations for new interactive UI.\n\n### Risks and owner-confirmation boundaries\n\n- The owner has explicitly approved the issue's >400-line implementation budget.\n- Stop for owner confirmation before adding a dependency, changing a shipped\n package API/runtime, changing release metadata, weakening accessibility or\n security behavior, or approving an intentional parity exception not already\n stated above.\n- Treat the live Island site as the visual/content reference and the current\n package implementation/types as the source of truth for modern API facts.\n- Prefer shared data-driven documentation structures over duplicating large\n locale-specific React implementations.\n\n### Stop conditions\n\n- A requirement conflicts with the current public runtime/API and cannot be\n resolved as documentation-only work.\n- A required Island reference/baseline cannot be captured deterministically.\n- An in-scope check fails twice for causes outside the issue's changes.\n- Work would require a new dependency, release change, security-sensitive change,\n or product/API decision.\n- The implementation is complete and committed.\n\nStop after committing. Do not push, create a PR, or merge.\n",

+ "title": "docs: close the remaining Island UI and content parity gaps in Nextra",
+ "body": "## Context\n\nThis is a follow-up to #97 / #98. That work required the Nextra documentation to reproduce the established Island site exactly, with `https://echoui.dev/en/` as the visual source of truth. A fresh comparison against the current `dev` branch shows that the shell is closer, but substantial UI, information-architecture, and example-coverage differences remain.\n\nKeep Nextra. “Parity” here means preserving the Island presentation and documentation coverage while retaining factual improvements made for Echo UI 1.1.x (React 19, Tailwind CSS 4, Tone.js 15, accessibility, lifecycle, and error guidance). It does **not** mean restoring IslandJS, NextUI, stale setup instructions, or old implementation dependencies.\n\n## How to compare\n\n1. Run `pnpm dev:docs`.\n2. Compare the same English and Chinese routes against `https://echoui.dev/en/` and `https://echoui.dev/zh/`.\n3. At minimum, inspect `/`, `/guide/introduction`, `/guide/about`, `/component/button`, `/component/knob`, `/component/spectrogram`, and `/hook/usePlayer`.\n4. Compare 1440×900 and 390×844 in both light and dark themes.\n\n## Observed differences\n\n### 1. Site shell and navigation\n\n| Area | Island reference | Current Nextra site |\n| --- | --- | --- |\n| `/` | Redirects directly to `/en` | Shows a separate editorial “Choose your documentation language” landing page |\n| Links menu | GitHub, Discord, Twitter | Discussions, Issues, Discord |\n| Guide sidebar | Shows a `Guide` group heading and a separated `About` group | Renders a flat four-link list |\n| Contribution/navigation affordances | Exposes “Edit this page on GitHub”, last-updated metadata, and previous/next page navigation | `editLink={null}` and `navigation={false}`; only the timestamp remains |\n| Footer | Island configuration contains license/copyright and page navigation metadata | The Nextra footer is mounted but globally hidden |\n| External links | Plain Island link treatment | Nextra adds external-link arrow glyphs throughout prose |\n| Callouts | Neutral Island bordered panel | Blue Nextra info callout with icon and different spacing/color |\n\nThere is also a content/implementation contradiction: the Declaration page says readers can use “the edit link on each page”, while the layout explicitly disables edit links.\n\nRelevant files:\n\n- `docs/app/[lang]/layout.tsx`\n- `docs/app/[lang]/island-theme.css`\n- `docs/app/(landing)/page.tsx`\n- `docs/content/en/_meta.ts`\n- `docs/content/zh/_meta.ts`\n- `docs/content/*/guide/declaration.mdx`\n\n### 2. Guide content and hierarchy\n\n- Introduction feature bullets became five H3 sections. This materially changes page length, scan rhythm, and the table of contents.\n- All guide copy was rewritten rather than migrated in place. Some updates are useful and should remain, but the result is not content parity with the Island reference.\n- About removed the WeChat community option and QR code even though `wechat.jpg` is still shipped as a public asset.\n- Installation is correctly modernized for 1.1.x, but its presentation no longer follows the four-step Island structure.\n- The root language-selection page introduces a visual language that does not exist anywhere in the Island site.\n\n### 3. Component example coverage was reduced\n\nThe Island source had 30 files under `docs/src/components/UsageBox` and `docs/src/components/Example`. The current site consolidates the documentation into a small set of shared demo files and generally renders one demo per component page.\n\n| Component | Island examples no longer shown as equivalent live variants |\n| --- | --- |\n| Button | default, toggled, disabled, sizes, radii, group |\n| Checkbox | default, disabled, sizes, colors, group |\n| Envelope | ADSR, AHDSR, DADSR/delay |\n| Input | default, disabled, bilateral, text, sizes, radii, progress color, min/max, step/sensitivity |\n| Knob | default, disabled, bilateral, rotation range, labels, step/sensitivity, sizes, colors, group |\n| Radio | default, disabled, sizes, colors, group |\n| Slider | default, disabled, vertical, bilateral, axis, step, custom styling, uncontrolled |\n| Switch | default, toggled, disabled, sizes, custom styling |\n| LFO | default and delay |\n| Light | default, on, colors, sizes |\n| Spectrogram | default, axis, grid, EQ3 scenario |\n| VU Meter | default, horizontal, stereo, compact, segment count, custom colors |\n| Card | default, active, real-world scenario |\n\nOscilloscope and Waveform still have a live example, but they also lost the Island example affordance described below.\n\n### 4. The example and API presentation is different\n\n- Island gives every example a `Preview` / `Code` switch. The current demo frame has only a `Preview` label; source is no longer available beside each rendered variant.\n- Current demos add useful live status and more realistic audio flows, but they replace rather than supplement the variant matrix above.\n- Island API tables use `Attribute / Description / Type / Default`; current tables use `Prop / Type / Default / Description` and add a new inherited-props paragraph.\n- Dedicated Data Attributes/Data Tags sections were removed from most component pages. The current docs only surface a small subset (for example VU Meter `data-active` and Card `data-toggled`).\n- Full type-declaration blocks were removed in favor of generated API tables. Keep the tables if they are complete, but restore any public contract details that are no longer discoverable.\n- Hook pages gained live demos, lifecycle, and error guidance; preserve those improvements while matching the Island visual hierarchy and API discoverability.\n\nRelevant files:\n\n- `docs/app/_components/controller-demo.tsx`\n- `docs/app/_components/display-*.tsx`\n- `docs/app/_components/hook-demo.tsx`\n- `docs/app/_components/*-api.tsx`\n- `docs/app/_components/*-docs.module.css`\n- `docs/content/{en,zh}/component/*.mdx`\n- `docs/content/{en,zh}/hook/*.mdx`\n\n## Why the current regression check misses this\n\n`scripts/verify-docs-ui.mjs` compares the current site with hand-written style constants. It does not compare the output with an Island screenshot/DOM baseline. It verifies the shell mainly through the Button route and only requires each component route to contain at least one demo, so it cannot catch reduced example coverage, changed copy/hierarchy, missing links, or changed root behavior.\n\nThe two files under `docs/screenshots/` are unreferenced migration-preview captures, not Island parity baselines.\n\n## Acceptance criteria\n\n- [ ] Create and document an Island → Nextra parity matrix covering shell, navigation, content hierarchy, examples, API/data-attribute coverage, and intentional modernized exceptions.\n- [ ] Match the Island shell at 1440×900 and 390×844 in English/Chinese and light/dark themes, including the root-route behavior, sidebar grouping, callouts, link treatment, and page-level navigation affordances.\n- [ ] Restore the Island Links destinations, edit-page affordance, previous/next navigation, and footer behavior, or explicitly document an approved product decision for each deviation.\n- [ ] Fix the Declaration copy so it agrees with the actual edit-link behavior.\n- [ ] Give every Island component variant an equivalent live preview and adjacent copyable source, unless its removal is explicitly approved in the parity matrix.\n- [ ] Restore missing Data Attributes/Data Tags and public type/API details.\n- [ ] Preserve the current 1.1.x installation, Tone.js 15, accessibility, lifecycle, error-handling, and real-audio-demo improvements.\n- [ ] Replace the current style-constant-only check with maintained Island visual baselines (or an equivalent deterministic comparison) for representative guide, controller, visualization, Hook, and home routes.\n- [ ] Add content-inventory assertions for example labels/counts, Links destinations, edit/pagination controls, root behavior, and both locales.\n- [ ] `pnpm lint`, `pnpm typecheck:docs`, `pnpm build:docs`, and `pnpm test:docs` pass.\n\n## Out of scope\n\n- Reintroducing IslandJS, NextUI, or `react-live`\n- Reverting accurate Echo UI 1.1.x compatibility and API information\n- Removing accessibility or real Web Audio improvements solely to obtain pixel parity\n",

+# Issue #108 UI evidence
+
+Every scenario has one frozen-base capture in `before/` and one exact product
+state capture in `after/`. The manifest binds each pair to the same scenario,
+route, and viewport for mechanical validation.
+
+| Scenario | Route | Viewport | Evidence |
+| --- | --- | --- | --- |
+| `root-language` | `/` | 1440×900, light | The editorial language picker becomes an automatic redirect to `/en/`. |
+| `guide-introduction-pagination-footer` | `/en/guide/introduction/` | 1440×900, light | Previous/next navigation and the visible license/copyright footer are restored. |
+| `guide-about-wechat` | `/en/guide/about/` | 1440×900, dark | The About route regains its WeChat option and shipped QR image. |
+| `guide-mobile-navigation` | `/zh/guide/introduction/` | 390×844, dark | The localized mobile section navigation opens with its expanded state. |
+| `guide-locale-switch` | `/en/guide/introduction/` | 1440×900, light | The locale switch opens from the desktop header. |
+| `guide-theme-switch` | `/en/guide/introduction/` | 1440×900, light→dark | The theme control applies the dark document theme. |
+| `guide-edit-link` | `/en/guide/introduction/` | 1440×900, light | The page-level GitHub edit control is visible. |
+| `controller-button-code-copy` | `/zh/component/button/` | 390×844, light | Preview/Code switching and the localized source-copy success state are present. |
+| `controller-button-keyboard-reduced-motion` | `/en/component/button/` | 1440×900, light, reduced motion | Arrow-key tab focus is visible while reduced-motion emulation is active. |
+| `controller-knob-responsive` | `/en/component/knob/` | 390×844, dark | The complete Knob variant matrix fits without horizontal overflow. |
+| `visualization-spectrogram-links` | `/zh/component/spectrogram/` | 1440×900, light | Visualization variants render and the Links menu exposes GitHub, Discord, and Twitter. |
+| `hook-use-player-audio` | `/en/hook/usePlayer/` | 1440×900, dark | A real-audio action exposes the Hook demo’s runtime state and lifecycle UI. |
+
+The before images were captured from frozen base
+`9eea05360a90e46a4c66c2e821e9ad5bd6c71c67`. The after images were freshly
+captured from the repaired product at commit
+`7aa9454f8a5da1cb5045864fdf1b7350744ae8df` after `pnpm verify` completed.
+The evidence commit only reorganizes these PNGs; it does not change the rendered
+product state they record.
+
+Deterministic non-image checks complement the captures:
+
+- `tests/docs-rendered-visual-contract.test.ts` renders the five maintained
+ baseline categories across both locales, desktop/mobile, and light/dark (40
+ cases).
+- `tests/docs-example-frame.test.tsx` verifies arrow-key focus behavior, the
+ polite copy-status announcement, and Preview/Code semantics.
+- `tests/docs-parity.test.ts` verifies the reduced-motion CSS override,
+ navigation destinations, edit/pagination/footer controls, root behavior, and
+ content inventories.
