FASHIONISTAR — Global System Tests conftest
============================================
Located at:  tests/conftest.py  (one level below root conftest.py)

This file provides fixtures specific to SYSTEM-LEVEL tests:
  - tests/smoke/        → Site-wide health checks (DB, Redis, Celery, email)
  - tests/integration/  → Cross-app integration tests
  - tests/e2e/          → End-to-end full user journey tests

Inherits ALL fixtures from the root conftest.py automatically.

System test philosophy:
  - Smoke tests run on EVERY commit (CI fast-path)
  - Integration tests run on PR merge
  - E2E tests run on staging deploy
