@* The ALL-tab content (Phase 9 §8.B): the cross-medium all-releases grid (CUTS, SESSIONS, MIXES
|
|
together) with per-row edit, delete, expand-tracks, and the 8.D Type chip. Self-contained — owns its
|
|
own data load so a host (TrackList today, the 8.A tab strip later) renders it with no parameters and
|
|
no VM plumbing. Re-loads on first render and re-fetches after a row mutation so the list stays in
|
|
sync with the catalogue. *@
