- Add `seasons__episodes__video_files` and `seasons__episodes__external_sources` to `prefetch_related` in `AnimeViewSet`. - Reduce queries for Anime Detail from ~25 to ~7 (1 query per relation instead of 1 per episode). - Fix `content/serializers.py` to match current models using `source` mapping to preserve API contract (e.g. `file_url` -> `hls_path`). - Add regression test `content/tests/test_anime_detail_performance.py`. - Add missing `djangorestframework-simplejwt` dependency to `requirements.txt`.
