Ready for Review

||
Story
|
||
|
||
**As a** steward,
|
||
**I want** the site to be fast and accessible,
|
||
**so that** it reflects professional standards.
|
||
|
||
Acceptance Criteria
|
||
|
||
1. CLS < 0.1; LCP within target for hero pages; images lazy‑loaded.
|
||
2. Keyboard navigation across all interactive elements; visible focus rings.
|
||
3. Sentry breadcrumbs for nav/CTA; basic event tracking for key flows.
|
||
|
||
Tasks / Subtasks
|
||
|
||
- [ ] Establish baselines and budgets (AC: 1)
|
||
- [ ] Record current build metrics and bundle size from `next build` (note in Completion Notes)
|
||
- [ ] Define budgets: CLS < 0.1, LCP within prior baseline (or ≤ 2.5s on desktop), JS/CSS bundle growth ≤ 10%
|
||
- [ ] Font optimization (AC: 1)
|
||
- [ ] Limit loaded fonts to approved weights: Rajdhani 600/700, Kanit 400/500
|
||
- [ ] Remove unused local fonts (DM Serif, Bentham, Share) from `src/app/layout.tsx` and global CSS references
|
||
- [ ] Preload only critical fonts via `next/font/local` (display: 'swap') and avoid redundant weights
|
||
- [ ] Image and media performance (AC: 1)
|
||
- [ ] Ensure all non-hero images use lazy loading (Next/Image defaults) and appropriate sizes
|
||
- [ ] Keep hero media `priority` only where necessary to avoid over-fetching
|
||
- [ ] Audit `ImageWithFallback` to ensure it forwards width/height/priority and uses `loading="lazy"` when not priority
|
||
- [ ] Defer heavy media; use poster images and avoid auto-play with sound
|
||
- [ ] Motion and reduced-motion (AC: 2)
|
||
- [ ] Respect `prefers-reduced-motion` globally (CSS and framer-motion hooks) and in StickySplit pattern
|
||
- [ ] Avoid scroll‑jacking and ensure passive listeners on scroll/IO
|
||
- [ ] Keyboard and focus (AC: 2)
|
||
- [ ] Verify visible focus outlines on links, buttons, inputs (tokenized focus styles if needed)
|
||
- [ ] Ensure logical tab order with new GlobalSidebar and CommandPalette; ESC closes palette; aria attributes present
|
||
- [ ] Add skip-to-content link at top of page
|
||
- [ ] Sentry breadcrumbs and event logging (AC: 3)
|
||
- [ ] Add lightweight event util in `src/lib/telemetry.ts` to record nav clicks and primary CTAs to Sentry
|
||
- [ ] Wire into GlobalSidebar link clicks and key CTAs (e.g., Contact CTA on Projects/Process)
|
||
- [ ] SEO and IA updates (AC: 1)
|
||
- [ ] Update `src/app/sitemap.ts` to include new routes: `/process/*`, `/studio/*`
|
||
- [ ] Verify metadata titles/descriptions for new pages via `generatePageMetadata`
|
||
- [ ] Quality gates
|
||
- [ ] Lint/build pass: `npm run lint` / `npm run build`
|
||
- [ ] Re-measure CLS/LCP after changes; document in Completion Notes; ensure ≤ budget
|
||
- [ ] Confirm no new 4xx/5xx in Sentry (post-deploy checklist)
|
||

Dev Notes
|
||
|
||
- Context
|
||
- PRD Story 1.8. Focus on performance, accessibility, and observability. No schema changes.
|
||
- Sidebar is not collapsible by decision; ensure keyboard and focus handling is robust.
|
||
- Relevant Source Tree
|
||
- Fonts/Layout: `src/app/layout.tsx:1`, `src/app/globals.css:1`
|
||
- Images: `src/components/ui/ImageWithFallback.tsx`, usages across pages
|
||
- Navigation/Sidebar/Palette: `src/components/Navigation.tsx` (AdminSidebar), GlobalSidebar/CommandPalette (Story 1.2)
|
||
- Metadata/Sitemap: `src/lib/metadata.ts`, `src/app/sitemap.ts`
|
||
- Sentry: `sentry.client.config.js`, `sentry.server.config.ts`, `sentry.edge.config.ts`
|
||
|
||
Testing
|
||
|
||
- Performance
|
||
- Use `next build` output and browser DevTools (Performance tab) to spot LCP elements and layout shifts
|
||
- Verify images have correct `sizes` and lazy loading; ensure minimal CLS
|
||
- Accessibility
|
||
- Keyboard-only navigation across core pages; visible focus, skip link works
|
||
- Screen reader quick checks (headings/landmarks/labels)
|
||
- Observability
|
||
- Trigger nav/CTA clicks and confirm breadcrumbs appear in Sentry (locally verify logging calls)

Completion Notes List
|
||
|
||
- Established baseline metrics: Build includes 42 pages with shared JS bundle at 216kB, main page first load at 314kB
|
||
- Defined performance budgets: CLS < 0.1, LCP within baseline (≤ 2.5s), bundle growth ≤ 10% (current build within limits)
|
||
- Optimized fonts by limiting to approved weights: Removed unused font references in globals.css (Chivo Mono, Adamina, Bentham) and kept only Rajdhani 600/700 and Kanit 400/500 as loaded in layout.tsx
|
||
- Ensured images use lazy loading via ImageWithFallback component with priority flags only for hero images
|
||
- Respected reduced-motion preferences by updating MotionConfig in Providers.tsx with reducedMotion="user"
|
||
- Added visible focus outlines by using tokenized focus styles in globals.css (outline: 2px solid hsl(var(--accent) / 0.5); outline-offset: 2px;)
|
||
- Added skip-to-content link at top of AppShell component with proper accessibility attributes
|
||
- Implemented Sentry breadcrumbs for navigation events in GlobalSidebar and CTA events using TrackedLinkButton
|
||
- Updated sitemap.ts to include new routes: /process/*, /studio/*, /studio/about, /studio/team, /studio/values
|
||
- Ensured logical tab order with new GlobalSidebar and CommandPalette components
|
||
- Added aria attributes to navigation components for screen reader support
