movie_detail/series_detail fetch credits, videos and external ids in one upstream request via append_to_response; cast is truncated to the top 10 billed in the crate and a trailer is chosen by rule (official YouTube trailer, any YouTube trailer, YouTube teaser, none). movie_videos/series_videos serve #144's search-row chip from the videos endpoint alone. Everything rides the existing 24h cache.
