Greptile SummaryThis PR improves accessibility, adds a high-contrast mode, and audits i18n coverage across settings and setup screens. All previously flagged issues (persistence of high contrast, wrong "Ready" badge text) have been addressed in the latest commits.
Confidence Score: 5/5Safe to merge — the changes are well-scoped accessibility and i18n improvements with correct persistence of the new high contrast preference. The high contrast round-trip (Rust model → hydration → Zustand → CSS → UI toggle) is correctly implemented end-to-end, previously flagged issues with the "Ready" badge text and missing persistence have been fixed, all new i18n keys are present in both locale files, and accessibility attributes follow established patterns throughout the form. No files require special attention. Important Files Changed

The frontend setHighContrast calls api.setSetting("highContrast", ...)
but the Rust SettingKey enum had no HighContrast variant, so parse()
returned a validation error and the preference was never persisted.
Add HighContrast to SettingKey, AppSettings.high_contrast, parse(),
as_str(), apply_setting(), entries(), and the known-keys test. The
setting now round-trips through SQLite and loads on hydration.

Accessibility:
- Add aria-describedby on all form inputs to associate validation
errors with their fields (prompt, lyrics, duration, bpm, negative
prompt, inference steps, guidance scale)
- Add aria-expanded to Collapsible and FailedRunsDrawer toggle buttons
- Improve --color-text-dimmer contrast: #7a7a82 → #8a8a8e (light),
#6f7780 → #858d96 (dark), #66666d → #808087 (darker) — meets WCAG AA
High contrast mode:
- Add highContrast store state + setHighContrast action
- Add toggle in Settings > General
- Add [data-high-contrast] CSS that raises --color-text-dim and
--color-text-dimmer for users who need stronger contrast
- Toggle applies data-high-contrast attribute on <html> via useEffect
i18n audit:
- Remove all defaultValue fallbacks from t() calls in settings sections,
SetupScreen, LogsSection, NetworkActivitySection — every string now
goes through the locale files
- Add missing keys: noNetworkActivity, networkTime, networkMethod,
networkUrl, networkStatus, anonymousErrorReports(+Description),
downloadedBadge, shortcutsHint, shortcut_{toggleSidebar,newGeneration,
toggleSettings,submitGeneration,togglePlayback}
- Add zh-CN translations for all new keys
- Add ja-JP/ko-KR feasibility notes in i18n.ts
Tests updated to assert on i18n keys instead of defaultValue strings.
Closes #61
