+Revision ID: 0047_plex_collections
+Revises: 0046_plex_people_search
+Create Date: 2026-07-06
+
+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.
