Review Summary — PR #132 (Issue #98: Accessibility Settings)
Overall Assessment: Request Changes
The core accessibility implementation is well-architected and thorough. The store ↔ hook ↔ CSS attribute pattern is clean, the pre-paint script in index.html prevents flash-of-wrong-theme elegantly, and the useInterpolatedTd reduced-motion path (1 Hz snap via setInterval) is a smart approach. Test coverage is solid with 14 new tests across three files.
However, there are two issues that need to be addressed before this can be merged.
🔴 Blocking: Out-of-scope changes (TutorialOverlay + tutorial-pulse CSS)
This PR includes changes unrelated to Issue #98:
src/components/GameLayout.tsx— imports and renders<TutorialOverlay />(belongs to Issue #97: FTUE/Tutorial)src/global.css— adds@keyframes tutorial-pulseanimation (also Issue #97)
While TutorialOverlay already exists on main so there's no build risk, PRs should be scoped to their issue. Please remove:
- The
TutorialOverlayimport line in GameLayout.tsx - The
<TutorialOverlay />JSX usage in GameLayout.tsx - The
@keyframes tutorial-pulseblock in global.css
These can ship as part of an Issue #97 PR.
🔴 Blocking: CI has not run
CI shows total_count: 0 / state: pending — no checks have executed on the head commit (5735c74). Per our CI gate policy, merging is blocked until all checks complete and pass. Please verify CI is triggered and green.
✅ What looks good
- Store design:
reducedMotionandhighContrastfields with dedicated setters;getOsReducedMotion()seeds the default fromprefers-reduced-motion— exactly right. - Hook composition:
useReducedMotioncorrectly ORs three sources (OS preference, legacyanimationsDisabled, newreducedMotiontoggle) into a single boolean. Clean single-responsibility. useHighContrast: Lean effect-based hook that syncs a DOM attribute. Called once at root. No over-engineering.useInterpolatedTd: The reduced-motion branch cancels RAF and falls back tosetInterval(1000)— fulfils the "TD counter jumps once per second" AC without complexity.CrtOverlay: Simple guard clause to disable scanlines under reduced motion.- Pre-paint script:
index.htmlinline script reads from the same Zustand persist key with proper try/catch — prevents white→black flash for returning high-contrast users. - CSS: High-contrast overrides are well-scoped under
[data-high-contrast="true"]with clear color choices (black bg, white text, yellow interactive, terminal green ASCII). - SettingsPanel: Nice reorganisation into ACCESSIBILITY / DISPLAY / AUDIO & NOTIFICATIONS sections with dividers.
- Tests: 14 new tests cover store fields, hook DOM sync, and toggle reactivity. Good coverage of both directions (on→off, off→on).
💬 Nit (non-blocking)
global.css — [data-high-contrast="true"] .float-particle: This rule hides particles and disables animation in high-contrast mode. High contrast ≠ reduced motion — a user may want high contrast colors but still enjoy animations. Consider gating particle animation only on [data-reduced-motion] or the existing prefers-reduced-motion media query, rather than tying it to high contrast. Not a blocker, but worth considering for correctness.
Action needed: Remove the three out-of-scope TutorialOverlay/tutorial-pulse additions, ensure CI is green, and this is ready to merge. The accessibility implementation itself is excellent.

nit: This rule disables particles in high-contrast mode, but high contrast ≠ reduced motion. A user might want high-contrast colors while still seeing animations. Consider gating particle visibility only on reduced-motion preference rather than high-contrast mode.

AshDevFr#132 Remove TutorialOverlay import and JSX usage from GameLayout.tsx, and tutorial-pulse keyframes from global.css. These belong to Issue AshDevFr#97 (PR AshDevFr#131), not Issue AshDevFr#98 (accessibility settings). Also fix Biome noInnerDeclarations errors in index.html by hoisting var declarations to the script root.

Re-review — PR #132 (Issue #98: Accessibility Settings)
Previous Blocking Items — ✅ Both Resolved
- Out-of-scope Issue #97 code removed — No TutorialOverlay import, JSX, or
tutorial-pulsekeyframes remain. The diff is now cleanly scoped to Issue #98 only. - Biome
noInnerDeclarationsfixed —index.htmlinline script now hoistsvar stored, parsed;at the top of the script block before thetry, satisfying Biome's linting rule.
Code Quality — Excellent
Store layer (settingsStore.ts): reducedMotion and highContrast fields added with proper defaults, actions, and persistence. getOsReducedMotion() correctly handles SSR (typeof window === "undefined") and wraps matchMedia in a try/catch for resilience. The OS preference seeds the default on first load, which is the right UX pattern.
Hook design:
useReducedMotionnow cleanly ORs three sources (OS preference, legacyanimationsDisabled, newreducedMotiontoggle) into a single boolean — good single-source-of-truth pattern.useHighContrastis minimal and correct: reads store, syncs DOM attribute viauseEffect, called once at root. Clean separation of concerns.useInterpolatedTdproperly cancels the RAF loop when reduced motion is active and falls back to a 1ssetIntervalsnap. Thereduceddependency in the effect array ensures correct teardown/setup on toggle. No leaked timers.
UI (SettingsPanel.tsx): ACCESSIBILITY section placed at the top of the panel (good visibility), with clear descriptions. Existing toggles regrouped under DISPLAY and AUDIO & NOTIFICATIONS headings with dividers — improves overall settings organization.
CSS (global.css): High contrast overrides are well-structured. !important on interactive element colors is acceptable here — accessibility overrides are one of the few legitimate uses. ASCII art colors correctly flatten to terminal green with text-shadow: none. Mantine shell backgrounds go pure black.
Pre-paint flash prevention (index.html): Synchronous localStorage read before React hydrates prevents the white→black flash for returning high-contrast users. Defensive try/catch around storage access is correct. The var hoisting fix addresses Biome cleanly.
CrtOverlay: Returns null when reduced motion is active — simple and correct.
Tests — 14 New, Good Coverage
useHighContrast.test.ts(6 tests): DOM attribute sync, store reactivity, toggle on/off.settingsStore.test.ts(8 tests): Default values, setter isolation, no cross-field side effects.useReducedMotion.test.ts(2 tests): Store field integration with existing OS/legacy checks.
Tests verify behavior (DOM attributes, store state) rather than implementation details. Failure cases (toggle off after on) covered.
Acceptance Criteria — All Met
- Reduced Motion toggle in Settings
- Reduced Motion disables: particles, shake, ASCII animation, counter interpolation (1 Hz snap), CRT scanline
- High Contrast toggle in Settings
- High Contrast applies: black bg, white text, yellow interactive, terminal green ASCII
- Both persisted in localStorage, applied on startup (no flash)
- OS
prefers-reduced-motionseeds default - Changes apply immediately (no reload)
Verdict
APPROVED. Clean, well-tested accessibility feature. Will merge once CI is green.

CI Failed — Lint errors on commit b9c8c1a
Code quality is approved (see previous review), but CI is red — the npm run lint step failed. Here are the issues found:
❌ Blocking (format error — causes exit code 1)
src/hooks/useReducedMotion.test.ts:80 — Biome formatting: the object { reducedMotion: false, animationsDisabled: false } needs to be broken across multiple lines per Biome's formatter rules.
⚠️ Warnings (non-blocking but should be fixed while you're in there)
index.html:17:15—lint/complexity/useOptionalChain:parsed && parsed.state→ use optional chaining (parsed?.state).index.html:21:16—lint/correctness/noUnusedVariables: catch variableeis unused → use_eor omit it.src/global.css:344:18—lint/complexity/noImportantStyles:!importantoncolor: #ffff00 !importantis flagged. This one is arguably justified for accessibility overrides — if Biome still warns after review, a suppression comment is acceptable.
Fix
All issues are auto-fixable. Running npx biome check --write . should resolve them. Please push a fix commit.

Review Summary — PR #132 (Issue #98: Accessibility Settings)
Verdict: APPROVED ✅
Code quality was reviewed in a prior pass and all blocking feedback was addressed. This final commit (cdaa4c3) is a formatting-only fix for Biome compliance in useReducedMotion.test.ts.
CI Status: GitHub Actions CI completed successfully (31s). All checks green.
What was reviewed (prior pass):
- Reduced Motion toggle: correctly ORs store field, OS media query, and legacy
animationsDisabled— single source of truth viauseReducedMotionhook - High Contrast toggle: reactive DOM attribute sync via
useHighContrasthook, CSS custom rules for[data-high-contrast="true"] - Pre-paint flash prevention via inline
<script>inindex.html— good UX detail useInterpolatedTdcorrectly snaps to 1 HzsetIntervalwhen reduced motion active (no RAF loop)CrtOverlayreturnsnullunder reduced motion- Settings persistence in localStorage via Zustand store
- 14 new tests covering store fields, DOM attribute sync, and hook behavior
- All 7 acceptance criteria met
What looks good:
- Clean separation of concerns: store → hooks → components
- OS preference seeding for reduced motion default is a nice accessibility touch
- No debug logs, no commented-out code, no stale TODOs

Re-review — PR #132 (Issue #98: Accessibility Settings) — Post-Rebase
🔴 Blocking: Rebase removed TutorialOverlay and tutorial-pulse from main
The rebase onto current main (05b65c6) introduced an unintended regression. PR #131 (Issue #97: FTUE/Tutorial) has since been merged to main, which added:
src/components/GameLayout.tsx—import { TutorialOverlay } from "./TutorialOverlay"and<TutorialOverlay />renderingsrc/global.css—@keyframes tutorial-pulseblock
This PR's diff now removes both, because the earlier review-fix commit (which removed out-of-scope Issue #97 additions from this branch) conflicts with what PR #131 added to main. During the rebase, the conflict was resolved by keeping the branch's version (without TutorialOverlay), effectively deleting the tutorial feature.
Fix needed: Re-do the rebase and keep the TutorialOverlay import, JSX usage, and tutorial-pulse keyframes from main. Only this PR's accessibility changes (useHighContrast hook, store fields, CSS high-contrast rules, etc.) should differ from main.
🔴 Blocking: CI has not run
CI status shows total_count: 0, state: "pending" — no checks have executed on the rebased head commit (b52dd6d). Per our CI gate policy, merging is blocked until all checks complete and pass.
✅ Accessibility code itself remains excellent
The prior approval of the accessibility implementation still stands — the store design, hook composition, CSS, pre-paint flash prevention, useInterpolatedTd reduced-motion path, and test coverage are all solid. Only the rebase conflict resolution needs fixing.
Action needed
- Re-rebase the branch, preserving TutorialOverlay + tutorial-pulse from main
- Ensure CI runs and passes on the new head commit
- Push and ping for re-review

Re-review — PR #132 (Issue #98: Accessibility Settings)
Summary
Re-reviewed after the two follow-up fix commits that restore code dropped during a bad rebase onto main. All accessibility changes were previously approved; this re-review focuses on confirming the rebase fixes and CI status.
Rebase fix verification ✅
GameLayout.tsx—import { TutorialOverlay }and<TutorialOverlay />JSX usage are correctly restored. TheuseHighContrast()hook call from this PR remains intact alongside the restored tutorial code.global.css—@keyframes tutorial-pulsekeyframe is correctly restored. All high-contrast CSS rules from this PR remain intact below it.
Both fix commits (a793b47, 7e7c126) are clean, minimal, and scoped exclusively to restoring the dropped code — no regressions introduced.
CI status ✅
The check workflow completed with success on head commit 7e7c126. All gates pass.
