/* ══════════════════════════════════════════════════════════════════════════════════════════
   files.css — Seeker Files (public/tools/files.js, #view-files, classes sf-…). 6 Oct 2026.

   The layout is the mock-up Ava approved on 06/10 (layout A, "Library"): alerts and the team's
   folders in a side column, a filter bar above the file list, a drawer for one file, plain
   dialogs. Its colours and fonts are the Platform's own tokens (--e-…), so Seeker Files looks like
   the rest of the Platform rather than like the mock-up's stand-alone page.

   ⭐ Every rule starts with #view-files, for the reason given at the top of tools.css: index.html
   already styles .rk .note, .chip, .row and more, and a bare class would pick those up.
