+
+Tests /api/v1/auth/{forgot,reset}-password over real HTTP against the
+session-scoped uvicorn api_server:
+- POST /auth/forgot-password  - Anti-enumeration generic response
+- POST /auth/reset-password   - Token claim, JWT invalidation on success
+
+Uses DEBUG_RETURN_RESET_TOKEN so the raw token is returned in the JSON
+body — the api_server fixture sets TESTING=true and this env var is
+opted into for the test session below.
