render.yaml

# NOTE: The free Render plan uses an ephemeral filesystem — the SQLite
# database is wiped on every restart/redeploy. `npm run seed` re-creates the
# sample questions on each boot so the demo always works, but user-created
# questions and quiz history will NOT persist across restarts.
# For durable data, attach a Render persistent disk (paid) and point
# DB_PATH at its mount path, or migrate to a managed database.
