The mixed /trending/all chart is movie-heavy — TV was nearly absent (only
1 of the top 10 was a show). Split it like Netflix: 'Top 10 today' now holds
two ranked rails, Movies and TV Shows, from the dedicated /trending/movie/day
and /trending/tv/day charts (full 10 of each).
- client.trending(window, kind): single-type charts force the kind into
_disc_map (those endpoints omit media_type).
- engine.trending(window, kind): kind in the cache key.
- /discover/list: key=trending_movies_today / trending_tv_today, both treated
as single un-paged charts; inherit the same hide-owned + ranked rendering.
- frontend: one 'Top 10 today' group, two ranked shelves titled Movies / TV
Shows (group header carries the 'Top 10' framing).
