What does this change?

Fixes #99

Addresses the five accessibility issues identified in the issue:

  1. Dark mode border contrast: Increased --border, --input, and --sidebar-border from 220 12% 16% to 220 12% 40% in src/index.css. The contrast ratio against --background: 220 15% 6% is now 3.13:1 (and 3.02:1 against --card: 220 15% 8%), hitting the WCAG 2.1 3:1 non-text contrast requirement.
  2. Text below 12px: Replaced all instances of text-[10px] and text-[11px] across src/pages/PromptDetail.tsx, src/components/prompts/PromptCard.tsx, and src/components/prompts/SharePromptDialog.tsx with text-xs (12px / 0.75rem).
  3. Hardcoded black over user images: Replaced text-black on the mobile menu trigger in src/components/prompts/PromptCard.tsx with an accessible frosted button (rounded-full bg-background/80 hover:bg-background/90 text-foreground backdrop-blur-sm border border-border/50 shadow-sm), guaranteeing legibility over both dark and light user images.
  4. Reduced motion: Added a global @media (prefers-reduced-motion: reduce) block in src/index.css setting animation/transition durations to 0.01ms and scroll-behavior to auto.
  5. Delete confirmation modal: Replaced the raw hand-rolled fixed inset-0 modal in src/components/prompts/PromptCard.tsx with Radix UI Dialog, DialogContent, DialogHeader, DialogTitle, DialogDescription, and DialogFooter, giving it focus trapping, Escape-to-close, scroll locking, and accessible dialog roles.
  6. Accessibility automated tests: Added tests in src/components/prompts/PromptCard.test.tsx and src/accessibility.test.ts to assert contrast ratio >= 3:1, reduced motion styles, absence of sub-12px text, and dialog focus trap semantics.

Why?

  • Dark mode borders were virtually invisible at ~1.3:1 contrast against the background.
  • Sub-12px text made muted metadata difficult to read for people with low vision.
  • Hardcoded black icon without a solid backing became unreadable when overlaid on dark user-uploaded images.
  • Animations did not honor the system's prefers-reduced-motion accessibility setting for vestibular disorders.
  • The prompt delete action used a raw div modal lacking focus trap, Escape key handling, and ARIA dialog semantics.

How was it tested?

  • Added automated tests in src/components/prompts/PromptCard.test.tsx to verify Radix dialog accessibility and mobile menu overlay styling.
  • Added automated tests in src/accessibility.test.ts checking WCAG contrast ratio, prefers-reduced-motion declaration, and text sizing.
  • Ran all CI validation commands locally:
    • npm run lint (0 errors)
    • npm run typecheck (0 errors)
    • npm test (all 16 test files and 85 tests passed)
    • npm run build (production build succeeded)
    • npm run db:schema:check (up to date)

Checklist

  • npm run lint passes
  • npm run typecheck passes
  • npm test passes
  • npm run build passes
  • Any new root-relative asset (/foo.png) is in public/, not src/assets/
  • No credentials, keys, or .env files are included
  • I've read the CLA in CONTRIBUTING.md

Summary by CodeRabbit

  • Accessibility

    • Improved dark-mode border contrast for better visibility.
    • Added reduced-motion support, minimizing animations and disabling smooth scrolling when preferred.
    • Increased small text sizes to improve readability.
  • User Interface

    • Updated mobile prompt-menu styling and icon sizing.
    • Replaced the custom delete confirmation with a consistent accessible dialog while preserving existing actions and messaging.
    • Updated sharing, rating, and unrated-state labels for clearer presentation.
  • Tests

    • Added coverage for accessibility requirements, mobile menu styling, and delete-dialog behavior.

📝 Walkthrough

Walkthrough

The changes address accessibility issues in dark-mode contrast, reduced motion, minimum text sizing, mobile menu styling, and prompt deletion. The custom delete overlay now uses shared dialog components. Tests cover the updated accessibility rules and prompt interactions.

Changes

Accessibility rules and validation

Layer / File(s) Summary
Accessibility rules and validation
src/index.css, src/accessibility.test.ts
Dark-mode border variables use higher lightness values. Reduced-motion rules minimize animation and transition durations. Tests validate contrast, motion settings, and text utility sizes.

Prompt menu and delete dialog

Layer / File(s) Summary
Prompt menu and delete dialog
src/components/prompts/PromptCard.tsx, src/components/prompts/PromptCard.test.tsx
PromptCard uses shared dialog and button components for deletion. The mobile menu trigger styling and icon size are updated. Tests cover authenticated dialog opening, cancellation, and mobile styling.

Minimum text sizing

Layer / File(s) Summary
Minimum text sizing
src/components/prompts/SharePromptDialog.tsx, src/pages/PromptDetail.tsx
Share and rating labels now use text-xs instead of fixed text sizes below 12px.

The accessibility check can miss newly introduced sub-12px decimal text sizes. This is a narrow test-coverage gap that should be corrected before relying on the check for the stated sizing requirement.

Detect decimal arbitrary text sizes.

sub12pxRegex matches only whole-number values from 0px through 11px. A text-[11.5px] utility can pass this check. The optional decimal applies only to values below 12px, so it does not reject allowed 12.x values.

Proposed fix
-    const sub12pxRegex = /text-\[(?:[0-9]|1[0-1])px\]/;
+    const sub12pxRegex = /text-\[(?:[0-9]|1[0-1])(?:\.\d+)?px\]/;
