Before
After
1
Removed stacked safe area insets
Templates were double-applying safe-area-inset-top/bottom with extra 32px padding. Fixed across HomeTemplate, ScreenWithMetricBar, and ScreenWithoutMetricBar.
2
Removed extra 2rem bottom padding in Layout.tsx
Bottom padding changed from calc(5rem + env(safe-area-inset-bottom) + 2rem) to calc(5rem + env(safe-area-inset-bottom)). No more excessive whitespace on Android gesture nav.
src/components/Layout.tsx
- pb-[calc(5rem+env(safe-area-inset-bottom)+2rem)]
+ pb-[calc(5rem+env(safe-area-inset-bottom))]
Before
After
1
Added "Add First Book" CTA button
Books page empty state now has an actionable button guiding new users to add their first book. Improved copy: "No books added" with contextual description.

Empty state wrapped in atomic Card component
Consistent card styling with proper border, padding, and border-radius from the design system.

After
3
Journal page: Loading skeletons replace blank space
Atomic Skeleton components replace "Loading..." text. 6 pages updated: Books, JournalList, Progress, Community, Notifications, ProgressGallery.
4
5 pages now have contextual empty state CTAs
Books: "Add First Book", Journal: "Write First Entry", Community: milestone explanation, Notifications: "All caught up!", Progress Gallery: "Take First Photo".
1
Replaced hardcoded bg-white with bg-card
AppHeader and surface-card components now use semantic color tokens that adapt to dark mode automatically.
2
WCAG AA contrast compliance
Muted text improved: light mode L:47% → L:42% (darker), dark mode L:65% → L:70% (lighter). All text now meets 4.5:1 minimum contrast ratio.
3
prefers-reduced-motion support
Global CSS rule disables all animations for users with motion sensitivity. Confetti functions check preference before firing. WCAG 2.1 Level AA compliant.
4
Inline hex colors replaced with semantic classes
TodaySummaryCard, SyncLogDialog, BookMetadataSection, WeightCard all migrated from hardcoded hex to Tailwind semantic tokens (text-muted-foreground, text-warning, etc.)
src/index.css
- --muted-foreground: 215.4 16.3% 46.9%; /* fails WCAG AA */
+ --muted-foreground: 215 20% 42%; /* passes WCAG AA 4.5:1 */
src/index.css (new)
+ @media (prefers-reduced-motion: reduce) {
+ *, *::before, *::after {
+ animation-duration: 0.01ms !important;
+ transition-duration: 0.01ms !important;
+ }
+ }
1
Fixed Chip.tsx using invalid SPACING tokens
SPACING[6] and SPACING[10] don't exist in the design system. Replaced with proper Tailwind classes: px-2.5 py-1 gap-1.5.
2
Added consistent border to atomic Card organism
Card component now has border: 1px solid COLOUR.BORDER matching all other card components in the app.
3
Audit confirmed consistency
All card components verified: 16px internal padding (SPACING[16]), rounded-lg border radius (RADIUS.LARGE), consistent gaps and typography hierarchy.
src/components/Chip.tsx
- style={{ gap: SPACING[6], paddingLeft: SPACING[10] }} // Invalid tokens!
+ className="px-2.5 py-1 gap-1.5" // Valid Tailwind classes
1
Verified: Index.tsx already fully migrated
Uses HomeTemplate, atomic Card, Skeleton, ScrollToTopButton. All child components (TodaySummaryCard, DayNavigator, PriorityTaskList) use design tokens. No custom Tailwind overrides found.
2
Fixed HomeTemplate padding override bug
CSS padding shorthand was overriding the calculated paddingTop with safe area inset. Switched to individual padding properties.
1
New ErrorBoundary component
Class component with getDerivedStateFromError and componentDidCatch. Shows friendly fallback UI instead of white screen of death.
2
All routes wrapped in App.tsx
Every route (auth, onboarding, protected pages) is wrapped. Users see "Something went wrong" with "Try Again" and "Go Home" buttons. Error details shown only in dev mode.
src/components/ErrorBoundary.tsx (new)
+ <Card> "Something went wrong" </Card>
+ <Button onClick={onReset}>Try Again</Button>
+ <Button onClick={handleGoHome}>Go Home</Button>
Zod Input Validation
4 critical edge functions now validate all inputs before processing. Malformed JSON returns 400 Bad Request with specific field errors.
NEW: validation.ts
Standardized Error Types
Custom error classes: AIRateLimitError (429), AICreditsExhaustedError (402), AIGatewayError (502), ValidationError (400).
NEW: errors.ts
Retry with Backoff
Transient failures (429 rate limits) automatically retry with exponential backoff: 1s, 2s, 4s delays, max 3 attempts.
NEW: withRetry()
Database Constraints
day_number CHECK (1-75), unique reading sessions per book/day, trigger to clear AI enrichment when journal text is edited.
NEW: migration
1
Single-character usernames now display correctly
Previously, username "J" would show "U" as fallback. Now handles all cases: "" → "U", "A" → "A", "AB" → "AB", "Alice" → "AL".
src/components/AppHeader.tsx:114
- {username.slice(0, 2).toUpperCase() || 'U'}
+ {username.length >= 2 ? username.slice(0, 2).toUpperCase() : (username.toUpperCase() || 'U')}
