-- Initial schema for Chicken Babies R Us. Authoritative copy of the
-- tables + indexes + check constraints documented in
-- ``docs/ROADMAP.md`` (see "SQLite Schema (authoritative)").
--
-- Idempotency: every statement uses IF NOT EXISTS so re-running the
-- file on a partially-migrated database is still safe. The migration
-- runner also gates execution via the schema_migrations tracker, so
-- this belt-and-braces approach is defensive only.
--
-- No PRAGMA statements here: journal_mode = WAL and foreign_keys = ON
-- are applied per-connection via the SQLAlchemy connect-event
-- listener in ``app/db.py``. Setting them inside a migration file
-- would be a no-op on every connection except the one that ran the
-- migration, which is the opposite of what we want.
