- DRF defaults: SessionAuthentication, IsAuthenticated, JSON-only render/parse
- shared api package: IsOwner permission (audits denials) and an exception
handler that flattens every error body to the {detail} SPA contract
- products views rewritten as APIView with permission_classes; manual JSON
parsing and auth checks removed (DRF parser returns 400 on bad JSON)
- response shapes and status codes preserved; product tests use DRF APIClient
