2. // episodes, persons, genres (storage/mpackdb/, migrated by tools/migrate.hl, tracker.worldapi.org#2).
3. // Kept apart from watches.hl (the per-user watch state) and from components/show.hl (the page itself)
4. // so /unwatched and /schedule (tickets #5/#6, "reuse, don't copy") can import the same functions.

7. // created with is untested territory, hybriel#21 "opening a table rewrites its files") — a slug
8. // lookup is a linear scan of ~9500 shows, cheap for one page load.
