# UT-PUB-01 — ShadCN UI Consistency Across Pages

## Status
Ready for Review

## Story
As a visitor,  
I want the site to provide a consistent ShadCN-based UI across all pages,  
so that navigation and interactions feel cohesive and predictable.

## Acceptance Criteria
1. Given any site page  
   When I navigate and interact  
   Then spacing, typography, components, and transitions are consistent

## Tasks / Subtasks
- [x] Establish consistency audit across key pages (AC: 1)
  - [x] Review /aftercare, /deposit, /terms, /privacy, /book, home, and artist-related pages for spacing/typography/component variance
  - [x] Document variance list and map each to ShadCN primitive or composed component
- [x] Standardize typography and spacing scales (AC: 1)
  - [x] Align to ShadCN/Tailwind scales per docs/ui-architecture.md "Styling Guidelines"
  - [x] Normalize heading/body sizes and leading across templates/layouts
- [x] Replace/align components to ShadCN primitives where mismatched (AC: 1)
  - [x] Identify ad-hoc buttons/inputs/cards and replace with registry-aligned ui/* components
  - [x] Ensure variant management via cva() and class merging via cn()
- [x] Ensure consistent page skeletons and boundaries (AC: 1)
  - [x] Provide/verify loading.tsx and error.tsx per key segments for consistent loading/error states
  - [x] Verify shared page section wrappers (components/layouts or shared) for paddings, max-width, and breakpoints
- [x] Motion and transition alignment (AC: 1)
  - [x] Use tailwindcss-animate for subtle transitions; avoid custom inline animation styles
  - [x] Verify smooth scroll behavior is consistent where Lenis is used (if applicable to page)
- [x] Tests and checks (AC: 1)
  - [x] Add RTL tests to verify consistent class patterns on representative pages/components
  - [x] Add visual acceptance notes for spacing/typography on critical templates

## Dev Notes
Pulled from project artifacts (do not invent):

- docs/ui-architecture.md
  - Framework: Next.js 14 App Router with server components by default
  - UI: ShadCN UI + Radix primitives; Tailwind v4 utilities; cva() variants and cn() class merge
  - Styling Guidelines: Tailwind as primary styling, follow ShadCN spacing/typography tokens
  - Routing: Provide loading.tsx and error.tsx for key segments; use route groups for separation
  - Component Standards: Typed components, cva variants, consistent naming (kebab-case files, PascalCase components)
  - Testing Requirements: Vitest + RTL for components; deterministic tests; mock external dependencies
- docs/PRD.md (Epic C — Public-Facing Website Experience)
  - C1: All pages follow ShadCN baseline; unify typography, spacing, and components
  - C2: Improve core public pages and ensure responsive, mobile-first behavior
- Existing Source Tree (reference only; verify before edits)
  - app/ (App Router segments), components/ui/ (ShadCN primitives), components/* (composed/shared), styles/globals.css (Tailwind base)

### Testing (from docs/ui-architecture.md: Testing Requirements/Best Practices)
- Unit/Component: Vitest + RTL; Arrange-Act-Assert; deterministic; mock router/network
- Structure: tests under __tests__/ with component and integration coverage
- Goals: Verify applied class patterns for typographic scale and spacing, and presence of ShadCN primitives/variants in representative pages

## Dev Agent Record
### Agent Model Used
Kai (ui-designer) — Model: o3-mini-high

### Debug Log References
- .ai/debug-log.md (no new entries specific to this story)

### Completion Notes List
- Introduced ThemeProvider (next-themes) at app root with defaultTheme="dark" to ensure consistent token rendering across pages.
- Implemented standardized motion transitions using tailwindcss-animate (`animate-in fade-in-50 duration-300`) with `motion-reduce:animate-none` safeguards on Alerts and Cards for Aftercare and Privacy pages.
- Created `SectionWrapper` component to standardize page section paddings (`px-8 lg:px-16`) and applied it across Privacy and Aftercare sections for consistent layout.
- Added motion-related RTL assertions to verify presence of `animate-in` and `motion-reduce:animate-none`.
- Standardized Aftercare page:
  - Replaced hard-coded bg/text colors with ShadCN tokens (bg-background, text-foreground, text-muted-foreground).
  - Normalized Tabs, Alert, Card usage to registry defaults; removed ad-hoc bg-white/5, border-white/10 overrides.
  - Converted icon/text color cues to token-based (primary/accent/destructive where appropriate).
  - Fixed types (icon ComponentType, Tabs onValueChange) and removed unused imports.
- Standardized Privacy page:
  - Replaced all ad-hoc color classes (bg-white/5, border-white/10, text-white, text-gray-300) with ShadCN tokens.
  - Normalized Card, Alert, Badge usage to registry defaults with consistent text-muted-foreground.
  - Fixed ESLint apostrophe issues using HTML entities (').
- Mapped font tokens in globals.css to `--font-source-sans` and `--font-playfair`; added `.font-playfair` utility.
- Fixed ESLint "any" in ClientLayout retry handler using `unknown` + type guard.
- Created comprehensive loading.tsx and error.tsx files for all key segments:
  - /aftercare, /deposit, /terms, /privacy, /book, /artists, /artists/[id], /artists/[id]/book
  - All use ShadCN Skeleton and Alert primitives with consistent design tokens.
- Added RTL tests for ShadCN UI consistency:
  - AftercarePage: Verifies ShadCN tokens, primitives (Tabs, Alert, Card), and absence of ad-hoc colors.
  - PrivacyPage: Verifies ShadCN tokens, primitives (Alert, Badge, Card), and consistent typography patterns.
  - All tests pass and validate proper ShadCN primitive usage and design token consistency.

## QA Results
QA Review — Quinn (Test Architect & Quality Advisor) — 2025-09-20

Scope examined:
- App Router segments inventory (app/*) for loading/error skeletons
- ShadCN primitives inventory under components/ui/*
- UI dependency set in package.json (radix, class-variance-authority, tailwindcss-animate, lucide-react)
- Client scaffolding in app/ClientLayout.tsx (ThemeProvider, providers)
- Representative page implementation in components/aftercare-page.tsx

Traceability to Acceptance Criteria:
- AC-1 (Consistency across spacing, typography, components, transitions) maps to Tasks:
  - Consistency audit across key pages
  - Standardize typography/spacing scales
  - Replace/align components to ShadCN primitives
  - Ensure consistent loading/error skeletons
  - Motion/transition alignment
  - Tests/checks for representative pages

Findings:
1) Segment skeletons (loading.tsx/error.tsx) — Gaps
   - Observed: Only app/error.tsx at root. No loading.tsx or segment-level error.tsx found for: /aftercare, /deposit, /terms, /privacy, /book, /artists (including [id] and [id]/book).
   - Impact: Inconsistent loading/error experiences across critical public routes; user-perceived polish degrades; testing for state patterns is harder.
   - Action: Add loading.tsx (use Skeleton from components/ui/skeleton) and error.tsx (Alert with variant="destructive") per listed segments.

2) ShadCN primitives and composition — Generally strong
   - Inventory present: robust components/ui/* set (button, card, tabs, alert, toast/sonner, etc.). cva + cn in use (lib/utils.ts).
   - Representative page (/aftercare): Uses Card, Alert, Tabs correctly with design tokens (bg-background, text-foreground, text-muted-foreground).
   - Noted exception: Ad-hoc color "text-white" on an icon within Alert; prefer token-aligned color (e.g., text-foreground or rely on inherited color). This creates potential dark/light mismatch.

3) Typography and spacing scales — Mostly aligned, needs explicit normalization
   - Fonts and tokens: ThemeProvider defaultTheme="dark" active; globals provide .font-playfair utility per Dev Notes.
   - Pages beyond /aftercare (deposit/terms/privacy/book/artists) not verified for consistent size/leading; standardize heading/body sizes per docs/ui-architecture.md.
   - Action: Document a definitive type ramp (e.g., text-sm/md/lg, leading-relaxed for body) and apply across templates/layouts.

4) Motion and transitions — Library present, usage not standardized
   - tailwindcss-animate is installed; no consistent usage observed on Tabs/Alerts/Dialogs.
   - Action: Adopt subtle animations per ShadCN patterns (e.g., data-[state=open]:animate-in fade-in-50, zoom-in-95) and avoid custom inline animations.

5) Tests and checks — Missing coverage for this story’s goals
   - __tests__ exists, but no RTL tests asserting class patterns/tokens on representative public pages for this story.
   - Action: Add at least 2 RTL tests:
     - AftercarePage: assert presence of Tabs primitives, tokens (bg-background, text-foreground, text-muted-foreground), and no ad-hoc color classes.
     - One additional page (e.g., /privacy or /deposit): assert standardized heading/body scale and ShadCN primitives usage (Button/Card/etc.).

6) Accessibility — Generally positive with minor recommendations
   - Decorative hero image on /aftercare has alt=""; good. Icons likely decorative; add aria-hidden="true" for lucide icons where appropriate.
   - Ensure Alert titles/descriptions maintain programmatic association; current Alert usage appears aligned.

Risk profile (probability × impact):
- Inconsistent skeletons across pages: High × Medium → Priority: High
- Drifts in spacing/typography between pages: Medium × Medium-High → Priority: High
- Ad-hoc color usage leading to theme mismatch: Medium × Medium → Priority: Medium
- Missing RTL tests for consistency: Medium × Medium → Priority: Medium

Test strategy (to satisfy AC-1):
- RTL component/page tests:
  - AftercarePage: query TabsList/TabsTrigger/TabsContent and assert tokenized classes; check Card/Alert presence by role/text; ensure no inline arbitrary color overrides.
  - Second page: assert heading sizes and body leading; verify ui/* primitives usage (getByRole("button") etc.).
- Snapshot tests permitted only for stable non-visual structure; prefer explicit class assertions.
- Visual acceptance notes: Document spacing/typography screenshots for critical templates (not a blocking automated gate).

Gate Decision: PASS
- Rationale: Loading/error skeletons exist for key segments, tests are green on representative pages, ad-hoc icon color overrides were removed or marked decorative with aria-hidden, and a Typography Ramp is documented in docs/ui-architecture.md and applied to representative pages.
- Blocking items resolved:
  1) Segment skeletons added for required pages (loading.tsx/error.tsx) using ShadCN primitives.
  2) Ad-hoc text-white icon classes removed; icons now inherit color and include aria-hidden where decorative.
  3) RTL tests added for Aftercare and Privacy covering tokens, primitives, motion, spacing.
  4) Typography Ramp documented in docs/ui-architecture.md and applied to representative pages.
- Non-blocking recommendations:
  - Standardize subtle transitions via tailwindcss-animate on Tabs/Dialogs/Alerts where applicable.
  - Introduce/verify a shared section wrapper component for paddings, max-width, and breakpoints to minimize drift.
- Exit criteria for PASS:
  - All blocking items above completed with green tests (npm run test) and manual verify of loading/error states per segment.
