<objective>
Make every sync indicator actually animate (D-13). RESEARCH corrected the original CONTEXT.md assumption: `@keyframes spin` is ALREADY global in `tokens.css` (lines 140–147) and loads before any component mounts — so the spinner works. The real bugs are (1) `@keyframes pulse` is MISSING, so `LiveSyncIndicator`'s reconnecting dot (`animation: 'pulse 1.4s ease-in-out infinite'`) never animates, and (2) `PushPermissionPrompt.tsx` carries a redundant local `<style>` redefinition of `@keyframes spin` that should be removed for hygiene.

Purpose: Pure CSS/markup fix — no business logic, so a standard (non-TDD) plan. The animation presence is verified with `playwright-cli` (desktop Chromium) per the CLAUDE.md verification convention, with a grep gate confirming the keyframe is in the stylesheet.
Output: `@keyframes pulse` added to `tokens.css`; redundant `<style>` block removed from `PushPermissionPrompt.tsx`.

<artifacts_this_plan_produces>
NEW symbols introduced here (exclude from drift/convergence checks):
- `@keyframes pulse` in `apps/pwa/src/styles/tokens.css` (0%,100% opacity:1 / 50% opacity:0.4)
- Removal of the redundant local `@keyframes spin` `<style>` block in `PushPermissionPrompt.tsx` (deletion, not a new symbol)

  <name>Task 1: Add @keyframes pulse globally; remove redundant spin redefinition</name>
  <files>apps/pwa/src/styles/tokens.css, apps/pwa/src/components/PushPermissionPrompt.tsx</files>
  <read_first>
    - apps/pwa/src/styles/tokens.css — existing `@keyframes spin` (lines 140–147) and `@keyframes shimmer` (~131–138); match their format (no vendor prefixes, no `animation-fill-mode` inside the keyframe block)
    - apps/pwa/src/components/PushPermissionPrompt.tsx — the redundant local `<style>{` @keyframes spin ... `}</style>` block (lines ~357–363) to delete; the inline `animation: 'spin 1s linear infinite'` stays
    - apps/pwa/src/components/LiveSyncIndicator.tsx — `animation: 'pulse 1.4s ease-in-out infinite'` (~line 69) — the consumer that needs the new keyframe
    - apps/pwa/src/components/SyncStateToast.tsx — `animation: 'spin 1s linear infinite'` (~line 158) — already-working consumer, confirm unchanged
    - .planning/phases/06-ux-polish/06-RESEARCH.md §"Focus 5" (the corrected diagnosis) + .planning/phases/06-ux-polish/06-UI-SPEC.md §"Animation Contract" (exact pulse keyframe)
  </read_first>
  <action>
    In `tokens.css`, add a `@keyframes pulse` block (0%,100% opacity 1; 50% opacity 0.4) directly after the existing `@keyframes spin` block, matching the surrounding format. In `PushPermissionPrompt.tsx`, delete ONLY the redundant local `<style>` block that redefines `@keyframes spin` (lines ~357–363) — leave the component's inline `animation: 'spin ...'` style and all other markup intact, since the global definition in `tokens.css` already covers it. Do NOT touch `LiveSyncIndicator.tsx` or `SyncStateToast.tsx` (their inline `animation` references are correct and now resolve to global keyframes). Commit: `fix(06-04): add global pulse keyframe and drop redundant spin redefinition`.

  <action>
    Verification task (no code changes). Using the playwright-cli skill against desktop Chromium: (1) start the dev stack host-side per docs/deployment.md with DEV_AUTH_BYPASS=true; (2) trigger a sync so SyncStateToast renders its Loader2 spinner and observe it rotating (computed `animationName === 'spin'`, transform changing over time); (3) force LiveSyncIndicator into the reconnecting state (drop the SSE connection) and observe the reconnecting dot's opacity pulsing (`animationName === 'pulse'`, not 'none'); (4) confirm PushPermissionPrompt's spinner still rotates after its local keyframe block was removed. Capture the observed `animationName` for both indicators in the summary. This is a blocking human-verify checkpoint — pause for the operator's confirmation.

  <what-built>
    Global `@keyframes pulse` in tokens.css and removal of the redundant local spin keyframe. Both animations now resolve from the global stylesheet for every consumer regardless of mount order.
  </what-built>
  <how-to-verify>
    1. Start the dev stack host-side per docs/deployment.md (DEV_AUTH_BYPASS=true), then open the PWA in desktop Chromium via playwright-cli.
    2. Trigger a sync state so SyncStateToast renders its Loader2 spinner; observe the spinner is visibly rotating (computed transform changes over time / animationName === 'spin').
    3. Force the LiveSyncIndicator into the reconnecting state (e.g. drop the SSE connection) and observe the reconnecting dot's opacity pulsing (animationName === 'pulse', not 'none').
    4. Confirm PushPermissionPrompt's spinner (if surfaced) still rotates after removing its local keyframe block.

  <verify>
    <human-check>Spinner rotates and reconnecting dot pulses in desktop Chromium; both animationName values are non-'none'.</human-check>

  <resume-signal>Type "approved" or describe which indicator did not animate.</resume-signal>
  <acceptance_criteria>
    - SyncStateToast spinner shows a live rotation (animationName 'spin').
    - LiveSyncIndicator reconnecting dot shows a live opacity pulse (animationName 'pulse').
    - No console error about an undefined keyframe.
