|
Mirrors Plex collections locally so reads never hit Plex's slow (dual-language) collection queries.
|
||
|
|
A `plex_collections` table holds each collection's card metadata; membership is stored as GIN-indexed
|
||
|
|
`collection_keys` on the member movies (plex_items) and shows (plex_shows), so a collection can be a
|
||
|
|
combinable filter and a title's "collection strip" is a pure local lookup. `editable` marks the
|
||
|
|
(curated) collections we may later write back to Plex; everything is read-only by default.
