1. // components/myshows.hl — `/my/shows` (tracker.worldapi.org#7): every show the signed-in user follows,
2. // the one followed last on top. Creator's words: "trackers /my/shows that just ists the shows in desc
3. // order i followed them, small poster, title, last episode like s08e35". Each row: the small poster (the
4. // same `/posters/<name>` route + placeholder as the show page, shows.hl `posterUrlOf`: one `/posters/none` URL when the file is missing), the title linking
5. // to `/shows/<slug>`, and the LAST WATCHED episode as `S08E35` — the architect's reading (in the ticket):
6. // the highest season/episode number the user has watched of that show; nothing watched → no episode.
7. //
8. // Read-only page (no check icons, no click), so like /schedule it needs no `on server` face — `rows` is
9. // one server-side render from `session`. Since #13 SERIES only — the movies a user follows are /my/movies
10. // (components/mymovies.hl). Reused (not copied): `followsOfUser`, `insertByFollowDesc` (follows.hl),
11. // `watchesOfUser` (watches.hl), `showById`/`episodeById`/`posterUrlOf`/`episodeCode`/`titleWithYear` (shows.hl).
12. //
13. // COST: only the user's own follows and watches are touched — one fetch per followed show and one fetch
14. // per watched EPISODE (never a scan of all episodes/seasons of a followed show, unlike /unwatched): the
15. // followed shows go into a map first, then each episode watch's episode is fetched once and kept only
16. // if it is higher than that show's current best (measured on a copy of the real data, STATUS.md).
17. //
18. // tracker.worldapi.org#21 (mission 068): TWO lists from this one component — `/my/series` (the followed SERIES) and `/my/shows`
19. // (the followed SHOWS: reality, talk, news; shows.hl titleKind) — routed as `/my/:tv` (project.hl, after the other /my/ routes);
20. // any other word is "Not found". Each row links to the title's own page (shows.hl titlePath).
