/* SharePoint Archiver — Discovery dashboard (story 3-9 widgets 1-6 + story 3-10 widgets 7-8).
   Productionised from the approved mockup px-output/mockups/spa-discovery-dashboard.html.
   Palette is colour-blind-safe: Documents #2a78d6 / Media #eb6834 / Legacy #1baf7a / Other #9AA4A2.
   Red (--crit) is reserved for over-quota only. Theme follows prefers-color-scheme, with an explicit
   data-theme override. The version-history section (widgets 7-8, story 3-10) IS styled here -- see
   .vgrid/.tmwrap.wide/.keepstrip below -- this header was stale from 3-9 (LN-3 fix, 2026-09-20). */
