1. // components/schedule.hl — `/my/schedule` (tracker.worldapi.org#6, moved from `/schedule` in #8): every episode of a show the signed-in
2. // user follows that is not yet released, soonest first. Creator's words: "/schedule has a similar list
3. // without check icons for he upcoming episodes of shows followed". Same row shape as /unwatched (step 5)
4. // minus the check icon and minus any click handling — this page is read-only, so it needs no `on server`
5. // face at all. Reused (not copied) from follows.hl/shows.hl: `followedShowIds`, `cardOf`, `episodeRowsOf`
6. // — the same functions /unwatched already imports.
7. //
8. // Upcoming = release date strictly AFTER today (the architect's reading of the ticket: "the creator named
9. // the order only for /unwatched" — /unwatched is release <= today, so the natural complement here is
10. // release > today; an episode releasing today already belongs to /unwatched once watched state is added).
