"""
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.
