New feature: photograph a recipe card, cookbook page, or handwritten
note and have it extracted into a structured, editable recipe.
Backend:
- POST /recipes/scan: accept 1-4 photos, run VLM extraction, return
structured JSON for review (not auto-saved)
- POST /recipes/scan/save: persist a reviewed/edited recipe
- GET/DELETE /recipes/user: user-created recipe CRUD
- Vision backend priority: cf-orch -> local Qwen2.5-VL -> Anthropic BYOK
- 503 with clear config hint when no vision backend available
- Multi-photo support: facing pages (ingredients/directions) sent together
- Pantry cross-reference: marks which ingredients are already on hand
- migration 041: user_recipes table (title, servings, cook_time, steps,
ingredients JSON, source, pantry_match_pct)
- Tier gate: recipe_scan -> paid, BYOK-unlockable
Frontend:
- "Scan" button in the Recipes tab bar (camera icon)
- RecipeScanModal: upload step (drag-drop + file picker, up to 4 photos,
live previews), processing step (spinner), review/edit step (all
fields inline-editable before save), pantry match badge, warning banner
for low-confidence or incomplete scans
Tests: 35 new tests (23 unit + 12 API), 404 total passing
