"""
Tests for Stripe live-mode safety checks.

Covers the helpers added in `services/pricing_config.py`:
  - stripe_mode()           : detect 'live' / 'test' / 'unknown'
  - is_test_mode_in_production() : True if ENV=production but sk_test_…

These are pure functions on env vars, so they don't need any
database or HTTP setup.
