+tests/conftest.py
+-----------------
+Shared pytest fixtures + import-time environment setup.
+
+`config.py` calls `_require_env('SECRET_KEY')` and `_require_env('DATABASE_URL')`
+at *import* time, so those must be present in os.environ before `app` is
+imported anywhere. We set safe, throwaway values here (SQLite in-memory) so the
+whole suite can run with no MySQL, no Redis, no Stripe, and no real secrets.
+
+The pure-logic tests (SLA math, webhook helpers) never touch the DB. The
+routing-inertness test uses the in-memory SQLite engine only.
