# Tech tracking
tech-stack:
added: []
patterns:
- "SelectGroup + SelectLabel for grouped platform options in shadcn Select"
- "Collapsible per-slide pattern for Instagram carousel with open/close state per index"
- "Inline chip copy-feedback: setState(tag) for 1.5s then null — no toast required"
- "2-second copy-confirmed state for primary Copy button (setCopied + setTimeout)"
key-files:
created:
- ui/src/components/WallpaperGeneratePanel.tsx
- ui/src/components/WallpaperPreview.tsx
- ui/src/components/SocialPostPanel.tsx
- ui/src/components/SocialPostResult.tsx
modified:
- ui/src/pages/ContentStudio.tsx
key-decisions:
- "WallpaperBundle and AppIconBundle types defined locally in WallpaperGeneratePanel.tsx — no need for content-bundles.ts addition since these are consumed only by Wallpaper components"
- "SocialPostBundle type defined locally in SocialPostPanel.tsx — same reasoning"
- "ContentStudio.tsx created from scratch in this worktree (file exists on phase-42 base branch but not yet in worktree HEAD) — copied base then extended with Wallpapers + Social tabs"
patterns-established:
- "Wallpaper/social panel pattern: same Card structure as DiagramGeneratePanel — textarea, select, button with spinner, progress bar, result or empty state"
- "Hashtag chip copy pattern: copiedTag state tracks which chip is showing CheckCheck, auto-reverts after 1.5s"
- "Carousel collapsible pattern: openSlides Record<number, boolean> with toggleSlide helper"
requirements-completed: [WALL-01, WALL-02, WALL-03, WALL-04, SOCIAL-01, SOCIAL-02, SOCIAL-03]

# Phase 42 Plan 05: Wallpaper and Social UI Panels Summary
**Four React components + extended ContentStudio tabs: wallpaper generator with 12-platform grouped selector and multi-size app icon grid, social post generator with live character count and hashtag chip copy, carousel collapsible slides**
## Performance
- **Duration:** ~3 min
- **Started:** 2026-04-04T22:17:52Z
- **Completed:** 2026-04-04T22:21:00Z
- **Tasks:** 2
- **Files modified:** 5 (4 created, 1 modified)
## Accomplishments
- Created WallpaperGeneratePanel with PLATFORM_DIMENSIONS (12 entries) grouped into Desktop/Mobile/Social/App SelectGroups, SSE job tracking via useContentJob, and inline progress bar
- Created WallpaperPreview handling both wallpaper-bundle (image + Download PNG + resolution badge) and app-icon-bundle (responsive 2/3/5 col grid per size with individual download links)
- Created SocialPostPanel with PLATFORM_CHAR_LIMITS (4 platforms), live char count turning text-destructive over limit with aria-live="polite", Generate Post button
- Created SocialPostResult with read-only post card, Copy Post button (2s "Copied!" feedback), clickable hashtag chips (1.5s CheckCheck inline feedback), numbered Collapsible sections for Instagram carousel slides
- Extended ContentStudio.tsx from 3 tabs to 5: added Wallpapers and Social TabsTrigger + TabsContent following the exact existing pattern
## Task Commits
Each task was committed atomically:
1. **Task 1: Create WallpaperGeneratePanel and WallpaperPreview** - `5e0e024d` (feat)
2. **Task 2: Create SocialPostPanel, SocialPostResult, extend ContentStudio** - `07e15dc7` (feat)
**Plan metadata:** (docs commit — see below)
## Files Created/Modified
- `ui/src/components/WallpaperGeneratePanel.tsx` - Prompt + 12-platform grouped Select + Generate Wallpaper button + SSE job + PLATFORM_DIMENSIONS constant + WallpaperBundle/AppIconBundle type exports
- `ui/src/components/WallpaperPreview.tsx` - Image display with Download PNG, multi-size app icon grid with per-size download
- `ui/src/components/SocialPostPanel.tsx` - Prompt + 4-platform Select + live character count + Generate Post button + SSE job + PLATFORM_CHAR_LIMITS + SocialPostBundle type export
- `ui/src/components/SocialPostResult.tsx` - Post card + Copy Post + hashtag chips + Collapsible carousel slides
- `ui/src/pages/ContentStudio.tsx` - Added Wallpapers and Social tabs (5 total)
## Decisions Made
- Bundle types (WallpaperBundle, AppIconBundle, SocialPostBundle) defined locally in the panel component files rather than adding to content-bundles.ts. These types are only consumed by their respective panel/preview components — no cross-component sharing needed.
- ContentStudio.tsx written from the phase-42 base version (exists on gsd/phase-42 branch but not yet in this worktree's HEAD) with the two new tabs added.
## Deviations from Plan
None - plan executed exactly as written. All components match the UI spec copywriting contract. tsc compiles cleanly.
## Issues Encountered
None.
## User Setup Required
None - no external service configuration required.
## Next Phase Readiness
- All wallpaper and social UI components complete; ready for end-to-end testing once server-side renderers are live
- ContentStudio now has 5 tabs; Plan 42-06 (if it adds Convert tab) can follow the same TabsTrigger/TabsContent pattern
- WallpaperBundle, AppIconBundle, SocialPostBundle type exports available from component files if needed elsewhere
