/*
 * site.css — shared brand styling over Bootstrap 5.
 *
 * Brand palette ported from the legacy `Legacy_CodeRare_WebForms/CodeRareWebApp/Content/Site.css`.
 * The legacy app uses these colors:
 *   #D7230E   "rare red" — primary brand color, used on big CTAs and the chat header
 *   #C91F0D   rare-red hover
 *   #343a40   dark slate — top bar / side nav background
 *   #ccc      light gray — top-bar / side-nav text
 *   #5a2d82 → #7b4db5    admin-button purple gradient
 *
 * The legacy was Bootstrap 4 + Font Awesome 5; we're on Bootstrap 5. Utility-class
 * differences (ml-/mr- → ms-/me-, badge-* → bg-*-subtle) are handled per page —
 * this file only defines brand-tinted overrides.

 * Colour scheme:
 *   - GRADE (level + sub-tier): all grey. Evidence certainty is the "boring" axis.
 *   - Triage priority: muted version of the priority colour by default; hover = full
 *     colour; chosen = full colour + pressed indicator. Five colours pulled from the
 *     patient-record triage palette (P1 red → P5 teal).
 *   - Triage sub-priority: borrows the SELECTED priority's colour, same muted/hover/active
