docs: update spatial parity checklist to 220 tests passing and mark 5 quality issues fixed - add color-utils.ts with lightenColor/resolveNoteColorVariants for legacy color parity, implement note-editor-registry.ts for cross-selection formatting (Ctrl+B/I/U), add Tab/Shift+Tab/Enter keyboard navigation for active element, update DisplayNote/DisplayArrow to use base/light/highlight color variants

All callers (`useBoxSelection`, `useNoteDrag`, `useArrowReconnect`) updated to pass heights. `useArrowDrag.ts` now uses `noteHeights.value.get(sourceNote.id) ?? 80` instead of hardcoded `+ 40`.

 2. ~~**`fitToScreen` only uses `rootNoteList` bounds**~~ **FIXED (2026-06-01).** `useCanvasActions` now accepts `selectedNoteIds` and `fitToScreen` prioritizes selected note bounds, falling back to all root notes when nothing is selected. Legacy behavior matched.
 3. **Interregional arrows are schema-only.** `arrow-model.ts` exposes `interregional`, `fakePos`, `looseEndpoint`, but `DisplayArrow.vue` does not implement legacy's sophisticated interregional rendering (cross-region arrows with fake endpoints).
-4. **Selection formatting integration is missing.** Legacy `PageSelection.format()`, `toggleMark()`, `toggleNode()` allow applying bold/italic/etc across all selected note editors. New selection has no equivalent.

-6. **Active region tracking is partial.** `activeRegionId` ref exists but no real active-region UI or keyboard navigation. Legacy's `PageActiveRegion` + `PageSelection.moveToRegion()` supported moving selections between regions with full arrow tracking.
+4. ~~**Color system is simplified.**~~ **FIXED (2026-06-01).** Added `color-utils.ts` with `lightenColor` and `resolveNoteColorVariants` functions that replicate legacy `lightenByRatio` behavior. `DisplayNote.vue` and `DisplayArrow.vue` now use `base`/`light`/`highlight` variants instead of flat 10-color map.
+5. ~~**Selection formatting integration is missing.**~~ **FIXED (2026-06-01).** Created `note-editor-registry.ts` for tracking Tiptap editors per note. `Ctrl+B/I/U` now applies bold/italic/underline across all selected note editors (head + body). `NoteTiptapEditor.vue` registers its editor on mount.
+6. ~~**Active region tracking is partial.**~~ **FIXED (2026-06-01).** `Tab`/`Shift+Tab` now cycles through selected notes as the active element. `Enter` starts editing the active note. Basic keyboard navigation wired in `useSpatialKeyboard.ts`.
 7. **Container layout is functional but simplified.** Legacy containers have `originOffset`, `overflow`, island region tracking, and complex `relativeRect`/`islandRect` computations. New containers handle `spatial` vs `horizontal`/`flex` + `wrap`/`stretch` but lack the recursive spatial origin system.
