Style classifier (kiwi#27):
- app/services/recipe/style_classifier.py: LLM prompt with curated vocab,
cf-orch/LLMRouter fallback, JSON + regex tag extraction
- POST /recipes/saved/{recipe_id}/classify-style: Paid/BYOK tier gate,
fetches recipe from corpus, returns {suggested_tags:[...]}
- SaveRecipeModal.vue: "Suggest tags" button with loading state; merges
LLM suggestions into existing tags without overwriting user's choices
- 403/empty list silently ignored — button is a no-op when tier not met
Cooked leftovers shelf-life (kiwi#112):
- app/services/leftovers_predictor.py: deterministic FDA/USDA lookup table
with shortest-component-wins for proteins and dish-type override for
assembled dishes; special entries for ceviche (2d, acid != heat),
fermented/cured (kimchi 14d, confit/lardo 7d), soups, rice, pasta, etc.
- POST /recipes/{recipe_id}/leftovers: free tier, no gate
- RecipeDetailPanel.vue: shelf-life section appears after "I cooked this"
with fridge/freeze days, freeze-by advice, per-instance dismiss; calm
framing per no-panic UX policy
- LeftoversResponse Pydantic schema added to recipe.py
