/* Retired 2026-09-17 (M-003): dead weight, paired with the now-retired
   web/vedika-public/future-ui/collection-shell.js. Every selector this file
   declared (.collection-category, .collection-description,
   .collection-frame, .collection-grid, .collection-heading,
   .collection-menu, .collection-source, .collection-source-actions,
   .collection-tier) was created only by that script's dead mount(), which
   never ran (see collection-shell.js). Zero static uses of any of those
   class names exist anywhere else in web/vedika-public/. Content removed
   to stop shipping ~3.3KB of unmatched CSS to every dashboard page; file
   kept at this path for the same 404-avoidance reason as its script.
   Full prior source: `git log -p --
   web/vedika-public/future-ui/collection-shell.css`. */
