+# Index Page Redesign
+
+**Date:** 2026-05-20
+**Status:** Approved
+
+## Goals
+
+1. Make the index page hero background truly full-viewport-width.
+2. Align hero text and list content to the same horizontal position.
+3. Match the list content max-width to idea-post pages (1200px via `contentWrapper`).
+4. Replace the deprecated `antd/List` component with native HTML.
+5. Redesign list items in an editorial style — bold typographic, no avatars, no placeholder counts.
+6. Introduce a shared CSS token so hero text and list content are guaranteed to stay aligned.
+
+## Layout Structure
+
+The index page will set `fullWidthPage: true` via `useSetLayoutConfig()`. This removes the `max-width: 1200px` cap and side borders from `contentWrapper`, allowing the hero background to bleed edge-to-edge.
+
+Within the now-unconstrained page, both the hero text and the IdeaRoll use the same inner wrapper:
+
+```
+max-width: 1200px
+margin: 0 auto
+padding: 32px var(--content-padding-x)
+```
+
+This guarantees horizontal alignment regardless of viewport width.
+
+### Shared token
+
+Add to `src/style/colors.css`:
+
+```css
+/* Layout */
+--content-padding-x: 48px;
+--content-padding-x-sm: 24px;
+```
+
+Used in `index-page.module.css` for both `.heroInner` and `.listWrapper`. `--content-padding-x-sm` replaces `--content-padding-x` at `@media (max-width: 768px)`.
+
+### Hero restructure
+
+The `<section className={hero}>` gets a full-width background only. Text moves into a new `<div className={heroInner}>` that provides the constrained, centered inner wrapper.
+
+Before:
+```
+<section className={hero}>          ← background + max-width + padding
+  <p>breadcrumb</p>
+  <h1>Idea Board</h1>
+  <p>subtitle</p>
+</section>
+```
+
+After:
+```
+<section className={hero}>          ← background only, full-width
+  <div className={heroInner}>       ← max-width: 1200px, centered, padded
+    <p>breadcrumb</p>
+    <h1>Idea Board</h1>
+    <p>subtitle</p>
+  </div>
+</section>
+```
+
+## IdeaRoll: Editorial Item Design
+
+Replace `antd/List` + `List.Item` + `List.Item.Meta` with a native `<ul>/<li>`.
+
+Each item contains three rows:
+
+1. **Tag eyebrow** — `TagPopover` components inline, restyled as small-caps blue text. Dot separators (`·`) rendered in JSX between tags (never interactive).
+2. **Title** — `<a href={slug}>`, large bold dark text, no underline by default.
+3. **Byline** — `by [Author · Author] — [Dataset name]` (or `— No public dataset`). Small muted text.
+
+Items separated by a bottom border. No avatars. No star/message counts (removed entirely).
+
+### Tag rendering pattern
+
+```tsx
+{item.tags.map((tag, i) => (
+  <React.Fragment key={tag}>
+    {i > 0 && <span className={tagSeparator}> · </span>}
+    <TagPopover tag={tag} currentSlug={item.slug} className={eyebrowTag} />
+  </React.Fragment>
+))}
+```
+
+`TagPopover` receives an `eyebrowTag` className that overrides antd `Tag` default styles. The separator `·` is a plain `<span>` between tags.
+
+### Typography spec
+
+| Element      | Size | Weight | Color                         | Other                                          |
+| ------------ | ---- | ------ | ----------------------------- | ---------------------------------------------- |
+| Tag eyebrow  | 10px | 700    | `var(--primary-color)`        | uppercase, `letter-spacing: 0.15em`            |
+| Separator ·  | 10px | 400    | `var(--border-color)`         | `margin: 0 5px`                                |
+| Title        | 19px | 800    | `var(--primary-color)`        | `letter-spacing: -0.02em`, `line-height: 1.25` |
+| Byline       | 11px | 400    | `var(--text-secondary-color)` | —                                              |
+| Item border  | —    | —      | `var(--border-color)`         | bottom only, `1px solid`                       |
+| Item padding | —    | —      | —                             | `22px 0` top/bottom                            |
+
+## Files Changed
+
+| File                              | Change                                                                                                                                         |
+| --------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- |
+| `src/style/colors.css`            | `--content-padding-x` and `--content-padding-x-sm` tokens already exist (no code changes required in this PR)                                  |
+| `src/templates/index-page.tsx`    | Add `useSetLayoutConfig` + `fullWidthPage: true`; restructure hero with `heroInner` wrapper                                                    |
+| `src/style/index-page.module.css` | Rewrite `.hero` (bg only), add `.heroInner` (constrained wrapper), update `.listWrapper` to use token                                          |
+| `src/components/IdeaRoll.tsx`     | Replace `antd/List` with native `<ul>/<li>`; editorial item layout; remove `Avatar`, `StarOutlined`, `MessageOutlined` imports                 |
+| `src/style/idea-roll.module.css`  | Replace `.container` antd overrides with editorial styles; add `.listItem`, `.tagEyebrow`, `.eyebrowTag`, `.tagSeparator`, `.title`, `.byline` |
+
+## Out of Scope
+
+- `TagPopover.tsx` — no changes to component logic or popover behavior
+- `idea-post.tsx` / `idea-post.module.css` — untouched
+- Adding new data fields (date, type, program) to the IdeaRoll query
+- Any other pages
