1280e40eb2 Fix image generation model and purge logic 
- Change NanoBanana Pro model from gemini-3-pro-image-preview to gemini-2.0-flash-exp-image (previous model doesn't exist)
- Purge endpoint now deletes generated images from /app_data/images/ when soft-deleted presentations are purged
- Add purged_images counter to purge response

71ebbf3626 Fix layout-to-screenshot mapping in master deck parser 
In layouts mode, screenshots were matched by array index (0,1,2...)
which broke when PPTX had more slideLayouts than actual slides.
Now builds an explicit mapping from slideLayout filename to the
first slide that uses it, so each layout gets the correct screenshot.

e8295d6e71 Phase 4: Fix critical bugs, improve document parsing, add vision OCR 
- Fix SSE stream 500: use async_session_maker inside StreamingResponse generator
  (Depends session closes when endpoint returns, before streaming starts)
- Fix template application: store template_name in prepare endpoint so worker
  uses the selected custom template instead of defaulting to "general"
- Fix OverlayLoader: replace loading.gif with HamsterLoader component
- Fix parse_mode default: change from "slides" to "layouts" to avoid 70+ layouts
- Update Gemini Flash model to gemini-3.1-flash-image-preview
- Improve DOCX parsing: python-docx for structured table extraction, OCR enabled
- Add vision-based image text extraction via Gemini for uploaded images
- Add LayoutParser integration for slide layout structure analysis
- Add Phase 4 MVP features: transfer ownership, URL input, follow-up questions,
  attachment-to-slide mapping, content router

69a8829750 Phase 3: Bug fixes, feature enhancements, and polish 
P0 Critical: presentation isolation (client scoping), storage super_admin fix,
template selection in worker, IMAGE_PROVIDERS list fix.

P1 High: template layout management UI (delete/filter/bulk), slide-based parsing
mode, LLM model listing & connection test, settings persistence to DB (Fernet
encryption), logout button.

P2 Polish: storage improvements (master deck files, per-client breakdown, bulk
delete, hard purge, client selector), image generation error visibility
(__image_error__ badge), hamster wheel loading animation.

d3d1667a79 Phase 2: Admin panel, analytics, storage, template pipeline, multi-provider LLM 
- Fix admin sidebar: remove duplicate Teams, add Storage nav item
- Analytics: client-scoped queries, super_admin sees all (including NULL client_id)
- Storage management: list/download/delete presentations with file metadata
- Settings page with brand config router
- AI usage tracking: new AIUsageModel, ai_usage_service, analytics endpoint
- Master deck → template bridge: _register_as_template creates TemplateModel
  + PresentationLayoutCodeModel so parsed layouts appear in template picker
- Multi-provider LLM vision in parser: Anthropic/Google/OpenAI with asyncio.to_thread
- Fix PPTX upload 400: accept by .pptx extension (browser sends octet-stream)
- Fix reparse FK violation: presentation_id=None for parse_master_deck jobs
- Worker job_timeout increased to 1800s for LLM-heavy master deck parsing
- PYTHONUNBUFFERED=1 in docker-compose worker for real-time log output
- Auth: clientId in /me response, dev-login cookie improvements
- Frontend: auth slice clientId, master-deck thumbnails, storage page

a0d73b3b63 Phase 4: Generation Pipeline — brand enforcement, enhanced LLM calls, ARQ job queue 
- Step 14: Brand enforcement service (font/color/logo replacement, WCAG contrast check, LLM prompt context)
- Step 15: Enhanced outline & slide content generation with brand context, content summary, "no hallucination" instructions
- Step 15b: LLM auto-fallback retry logic across providers (FALLBACK_LLM_PROVIDERS env)
- Step 16: Redis/ARQ job queue — worker entry point, presentation & master deck workers, job status/SSE endpoints, graceful fallback to BackgroundTasks when Redis unavailable
