1. // components/show.hl — `/shows/:slug` (tracker.worldapi.org#4): a show's own page. Creator's words:
2. // "the poster on the left, right of it the title of the show, the genre pills, below the plot summary,
3. // below that the artists just as normal links, separated with comma color red, genres are blue" (the
4. // header) — "then all seasons in reverse order, latest on top, below them collapsable their episodes,
5. // episodes first the round check icon, if the episode was watched by the user looking its solid, if
6. // not its regular, then the episode number, then the title. the last season is not collapsed. click on
7. // the check adds a watch. the season also has a check, if the season is checked or unchecked all its
8. // episodes get checked or unchecked. artists link to /person/<artist-slug> the genre to /genre/<genre-slug>."
9. //
10. // THE ROWS ARE ONE FLAT LIST, not a nested for-loop over seasons > episodes: the vendored build may
11. // still lack the fix for hybriel#86 (a nested for over a reassigned outer list keeps stale inner
12. // cells) — a single-level `for (row of rows)` with a `kind` field, reassigned whole on every click,
13. // is the same proven-safe shape components/main.hl's own header and ident's inbox.hl already use.
14. // `rows` is rebuilt from scratch (seasons/episodes refetched by id, watch rows refetched) on every
15. // toggle — cheap: a show has at most a few dozen episodes per season.
16. //
17. // Mission 047 (the creator, 2026-10-01): a caret at the season header's right edge (down = open, right = collapsed); episode
18. // rows not indented; on a phone the title first, then the poster at full width, then genres/plot/cast; a Follow toggle
19. // next to the title. SIGNED OUT the checks and Follow are visible too: a click opens the "sign in" modal (modal.hl, copied
20. // from components.hybriel) and writes nothing.
21. //
22. // tracker.worldapi.org#17 (mission 057): the caret points DOWN while a season is closed and UP while it is open. Opening a
23. // season shows SKELETON rows at once (min(episodes, 8), a CSS shimmer, styles.hl) and then its episodes from the face
24. // `showSeasonEpisodes`, which takes NO session: a face with `session` makes hl:web re-mount the whole page on the server and
25. // ship every session-derived member back as a `sync` (WebFramework.hl `inbound`) — that, not the episodes, was most of the
26. // old 250–450 ms (real data). The watched state comes from `watchedEpisodes` (this show's watched episodes per season, rendered
27. // with the page and re-synced after every watch face). Closing is client-only (no request). An ADULT show (only its
28. // followers see it) keeps the session face `showRows`: the public face refuses adult seasons.
29. //
30. // tracker.worldapi.org#12: link icons under the title — the show on TMDB, IMDb, TheTVDB, TVmaze (a movie: TMDB + IMDb),
31. // only for the ids it has (shows.hl externalLinksOf), each in a new tab.
32. //
33. // tracker.worldapi.org#26: an INCOMPLETE title (one a person page added from a filmography — details.hl `needsDetails`) shows
34. // what it has plus skeletons (poster, cast line, season rows for a series) and completes itself WITHOUT a reload: the
35. // invisible `showProbe` (endless short CSS animation — hl:web has no mount hook, the person page's trick) calls the face
36. // `showComplete` until it is done — one step per call (details.hl completeStep: TMDB details + ids + cast; a series' seasons/
37. // episodes in parts; poster, TVmaze) — and the last answer's parts replace the skeletons. No session (no page re-mount); adult
38. // refused.
