Root cause of the doubled lists: the relay DB had stale rows from
previous activations that were never deleted. The composite PK
prevented same-uid duplicates but not leftover rows from cards that
were deactivated without a successful DELETE.
Fixes:
- Client tick sends DELETE { keep: [active uids] } after every
push cycle. The relay drops all rows for this tenant that aren't
in the keep list — cleans up migration leftovers, failed deletes,
old single-list sentinels, everything in one shot.
- Relay DELETE endpoint accepts { keep: [...] } for bulk cleanup
alongside the existing { card_uid } single-delete.
- Relay layout.php adds cache-busting query strings on style.css
and app.js via filemtime() so phone browsers pick up new code
on deploy instead of serving stale cached versions.
- showView persists the active view name to localStorage; after
login the relay restores it instead of always landing on compose.
- Shopping-list-box border/background removed — items have their
own chrome, the box is just a flex grouper now.
- View title is always "Shopping"; each list box keeps its own
header with the card title. No more doubled name.
