- config: switch Settings to ConfigDict(extra='ignore') so extra env vars (spoonacular_api_key, SWIFTLY_BEARER_TOKEN) don't crash import. Remove deprecated class Config. - email: wrap SendGrid imports in try/except so the module loads without the optional dependency. Update test_email_backend to patch Mail/RepyTo. - planner_select: default PlannerConfig.set_size=21 (3 meals/day × 7) is way too large for the unit test assertion that checks 3-recipe diversity. Introduced _CFG_3 with set_size=3 and applied to all tests. - Delete stale test_matcher.py importing removed functions. Full suite: 46 passed, 74 skipped (Postgres), 0 failed, 120 collected.
