"""Sprint 15 — Seed ~50 family-friendly recipes from Spoonacular.

User direction (2026-06-05): "Lets build out recipes for the coming
4 weeks in advance. In order to do this, lets add more recipes to
the list of available ones."

The script hits Spoonacular's complexSearch directly (avoids the
Sprint 12 /api/recipes/search route, which would otherwise count
the search against the backend's daily quota). For each query, it
takes the top hit and POSTs to the local backend's
/api/recipes/import endpoint (which does the 1-pt /information
call, the idempotent ingredient upserts, and the Recipe insert).

Idempotent: a 409 from the import endpoint means the recipe is
already in the local library; the script logs and continues.

Cost: 50 × complexSearch (~1.10 pts each = 55 pts direct) +
50 × /information (1 pt each = 50 pts, charged to backend
counter) = ~105 Spoonacular pts total. Free tier is 150/day;
backend counter has a 140-pt safety cap (140/150).

Run on the deploy host:
  ssh docker-willester
  cd /home/peter/MealPlanner
  source .env && export $(cut -d= -f1 .env | xargs)  # exports SPOONACULAR_API_KEY
  python3 scripts/seed_recipes.py
