   CapraSEO — Agents dashboard refinement (calm / premium pass)

   ADDITIVE + FULLY REVERSIBLE. Loaded LAST on /agents/ (after
   main.css → account.css → health.css → agents.css → chip-select.css)
   and every rule is scoped to body[data-page="agents"], so it restyles
   ONLY the Agents board and never leaks into other pages that share
   .card / .btn / .agent-icon / .ac-health.

   ► Turn OFF:  remove the single <link> to this file in agents/index.html.
   ► Tune it:   edit the --rf-* token block below.

   This pass follows the reference layout the user provided
   (the shared "Agents.dc.html" design — Linear-style dark cards,
   bordered status pills, larger accent icon tiles, mono numerals,
   generous vertical rhythm). Two deliberate deviations from that file:
     • Fonts stay Inter / JetBrains Mono (the reference's Geist would
       require bundling external font files).
     • Accent stays the app token --accent (var(--accent)); the reference's
       #5E6AD2 is near-identical and --accent is shared with the sidebar
       across every page, so per-page changes would desync nav highlights.

   Polish only — no layout, structure, copy, or hierarchy changes.
