/* ============================================================
   Demo — RFI Triage Brief
   BPS-04 RFI-register coordinator brief inside the Asite CDE
   chrome. A real agent writes the weekly RFI brief on demand;
   every claim is cited, a Top-5 of actions is proposed, and the
   draft emails are shown ready to review — sending is the human
   step. Selectors prefixed `rtb-`. Builds on main.css.
