# Dependency graph
requires:
  - phase: 43-01
    provides: pdf-document jobType, PdfDocumentBundle shape
  - phase: 43-02
    provides: brand-kit jobType, BrandKitBundle shape

provides:
  - DocumentGeneratePanel — docType select, title, prompt, pdf-document job, PDF download
  - BrandKitPanel — brand description prompt, brand-kit job, delegates to BrandKitResult
  - BrandKitResult — logo SVG, 5 avatar sizes, social images, email/letterhead iframes, guidelines PDF download, ZIP download
  - ContentStudio — 7 tabs including Documents and Brand

affects:
  - users who visit ContentStudio (Documents and Brand tabs now visible)

# Tech tracking
tech-stack:
  added: []
  patterns:
    - BrandKitBundle type defined in BrandKitResult.tsx and re-exported; BrandKitPanel imports the type from BrandKitResult (avoids duplication within UI)
    - PdfDocumentBundle defined locally in DocumentGeneratePanel.tsx (panel-local type pattern per project convention)
    - base64-to-blob download helper: Uint8Array.from(atob(b64), c => c.charCodeAt(0)) -> Blob -> createObjectURL -> <a>.click() -> revokeObjectURL
    - sandboxed iframes for HTML template previews: srcdoc + sandbox="allow-same-origin"

key-files:
  created:
    - ui/src/components/DocumentGeneratePanel.tsx
    - ui/src/components/BrandKitPanel.tsx
    - ui/src/components/BrandKitResult.tsx
  modified:
    - ui/src/pages/ContentStudio.tsx

key-decisions:
  - "BrandKitBundle type defined in BrandKitResult.tsx and imported by BrandKitPanel — avoids duplication within the UI layer while keeping type co-located with the display component"
  - "iframe sandbox=allow-same-origin for HTML template previews — prevents script execution in signature/letterhead HTML while allowing CSS rendering"

# Phase 43 Plan 03: Document Generation and Brand Kit UI Summary

**DocumentGeneratePanel, BrandKitPanel, BrandKitResult UI components with pdf-document and brand-kit job submission, PDF/ZIP download, and Documents/Brand tabs added to ContentStudio (7 tabs total)**

## Performance

- **Duration:** ~4 min
- **Started:** 2026-04-04T22:52:00Z
- **Completed:** 2026-04-04T22:55:22Z
- **Tasks:** 2 (Task 3 auto-approved as checkpoint:human-verify)
- **Files modified:** 4

## Accomplishments

- Created DocumentGeneratePanel with docType select (report/invoice/one-pager/api-docs), title input, prompt textarea, pdf-document job submission via useContentJob, progress bar, and PDF download (base64 blob)
- Created BrandKitPanel with brand description textarea, brand-kit job submission, progress bar, and BrandKitResult display on completion
- Created BrandKitResult displaying logo SVG preview, 5 avatar size grid, social images grid, sandboxed email signature and letterhead iframes, guidelines PDF download button, and prominent "Download Brand Kit (ZIP)" button
- Updated ContentStudio to import both new panels and add Documents and Brand TabsTrigger + TabsContent blocks — ContentStudio now has 7 tabs

## Task Commits

Each task was committed atomically:

1. **Task 1: Create DocumentGeneratePanel, BrandKitPanel, BrandKitResult** - `77d5b703` (feat)
2. **Task 2: Add Documents and Brand tabs to ContentStudio** - `f737b446` (feat)
3. **Task 3: Visual verification** - auto-approved (checkpoint:human-verify in autonomous mode)

## Files Created/Modified

- `ui/src/components/DocumentGeneratePanel.tsx` - PdfDocumentBundle type, docType select, title, prompt, pdf-document submit, PDF blob download
- `ui/src/components/BrandKitPanel.tsx` - brand description textarea, brand-kit submit, BrandKitResult render
- `ui/src/components/BrandKitResult.tsx` - BrandKitBundle type, logo/avatars/social/templates/guidelines display, ZIP download
- `ui/src/pages/ContentStudio.tsx` - DocumentGeneratePanel + BrandKitPanel imports, 2 new TabsTrigger + TabsContent blocks

## Decisions Made

- BrandKitBundle type is defined in BrandKitResult.tsx (the display component) and imported by BrandKitPanel — keeps the type co-located with what renders it and avoids duplication within the UI layer.
- iframe sandbox="allow-same-origin" used for email signature and letterhead previews — prevents arbitrary script execution while allowing inline CSS from the brand renderer's HTML output to render correctly.

## Deviations from Plan

None — plan executed exactly as written.

## Known Stubs

None — all data paths are wired to useContentJob which fetches real asset JSON from the server.

## Issues Encountered

None.

## User Setup Required

None — no additional configuration required beyond what Plans 43-01 and 43-02 already established.
