Three hand-copied panels had drifted: Add to playlist said a failed load as 'no playlists yet'. ui/MembershipMenu now holds them: a loading line and an error with Retry instead of a blank or an empty list, the up/down arrows step from the name field into rows that arrived after the menu opened, and the panels opened from a menu carry their own accessible name. A write that landed flips its tick at once, so a second tap before the refetch undoes it instead of repeating it; a collection edit also refreshes a show's own page.
"Add to collection…" opens a panel beside the card: the title's library's
manual collections tick it in or out, and a name + Enter creates a new one with
the title in it. It used to take the Collections page, a new collection, its
name and a title search, then another search per title. A lean endpoint lists
the collections with whether each holds the title. Admin only, as on the
title's page.
Also: a collection seeded with a show is made as a show collection (Plex type
2). Measured: as a movie one it came out empty and refused the show after.
