ae41562103 Phase 8: Data-driven slide architecture + template management overhaul 
Replaces TSX/Babel compilation pipeline with a JSON element model:
- New _do_parse_v2(): 1 LLM call/layout (vs 2) classifies OXML geometry
  elements into placeholder types → JSON stored in layout_code
- SlideRenderer.tsx: renders JSON element model as %-positioned divs,
  no Babel compilation or runtime errors
- parseLayoutSchema.ts: isJsonLayoutCode() / parseLayoutSchema() /
  mergeElementsWithContent() — full JSON schema parsing layer
- useCustomTemplates.ts: transparent dual-format support (JSON + TSX)
  via parsedLayoutToCompiled() adapter

Template management improvements:
- PresentationLayoutCodeModel: +is_enabled (bool) +thumbnail_path (str)
- Migration 005: adds both columns to presentation_layout_codes
- DELETE /master-decks/{id}: hard delete (files + TemplateModel +
  PresentationLayoutCodeModel rows + MasterDeckModel)
- PATCH /template-management/layouts/{db_id}/toggle-enabled: new endpoint
- LayoutData response: +db_id, +is_enabled, +thumbnail_path
- _register_as_template(): stores thumbnail_path + is_enabled per layout

Admin UI:
- /admin/templates/ — list all custom templates with delete
- /admin/templates/[id]/ — layout grid with screenshots + enable/disable
- AdminSidebar: Templates nav item

c431d4ab45 Implement critical security fixes and modern design system (Pre-launch P0 tasks) 
Security Improvements (P0.0-P0.4):
- P0.0: Migrate to Gemini-only AI stack (simplified, single billing)
- P0.1: Fix CORS to restrict allowed origins from env (was *)
- P0.2: Remove hardcoded dev password, require env var
- P0.3: Add rate limiting (slowapi) - 3-10 req/min on sensitive endpoints
- P0.4: Add request size limits (100MB default via middleware)

New Features:
- Unified LLM service with Google Gemini priority
- OXML geometry extractor for layout parsing
- TSX validator for generated React components
- Client ID support in presentation requests with access control
- Configurable LLM/image timeouts via env vars

Modern Design System (P0.9 - partial):
- Enhanced CSS design tokens (primary, semantic colors, shadows)
- Typography scale (h1-h4, body variants, caption)
- Modern animations (fadeIn, slideIn, scaleIn)
- Updated Button component with better variants and hover effects
- Created unified Card and StatusBadge components
- Applied design system to Dashboard and Settings pages

Backend Improvements:
- Master deck parser simplification
- Slide-to-HTML endpoint cleanup (325 lines removed)
- Better error handling in prompts endpoint

Frontend Improvements:
- Settings UI simplified to show only Google/Gemini
- Dashboard uses CSS variables instead of hardcoded colors
- Improved button transitions and hover states

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
