/* SecurityBox BYOA — Instrument conversation surface.
   Warm-graphite, mobile-first SOC product surface. Dark is the default (SOC context);
   a full light theme overrides the same custom properties under
   prefers-color-scheme: light. System font stack + inline SVG only — no CDN,
   no web fonts, no remote assets (air-gap friendly).

   Layout: single stacked column below 900px (list, then detail+chat once a
   conclusion is opened via the .has-selection collapse); a two-pane split at
   >=900px (fixed list left, detail+chat right). */
