"""Plex playlists (Siftlode-native, per-user, ordered)

Revision ID: 0048_plex_playlists
|
||
|
|
Revises: 0047_plex_collections
|

|
Create Date: 2026-07-06
|
||
|
|
|
||
|
|
Per-user ORDERED watch-lists of Plex items, kept in Siftlode's own DB so they work for users without a
|
||
|
|
Plex account (like plex_states) — the "your own lists" counterpart to the shared, library-level
|
||
|
|
collections. `plex_playlists` is owned by a user; `plex_playlist_items` holds the ordered entries
|
||
|
|
(`position`). `plex_rating_key` is reserved for an optional later Plex-direction sync.
