/*
 * Unified Communications — Portal stylesheet.
 *
 * Loaded by every public HTML portal. Mirrors the tokens defined in
 * backend/communications/tokens.js. Hex values appear here because email
 * clients strip <link> tags but browsers don't — portals can safely
 * reference a shared stylesheet.
 *
 * Brand direction:
 *   - Dark header bar (#0E1116) + 3px orange accent strip
 *   - Light body (#F7F4EF page floor)
 *   - White cards (#FFFFFF) with #E5E0D8 border
 *   - Mobile-first responsive (breakpoint at 640px)
 *
 * If a portal needs a one-off style, define it in a small inline <style>
 * block in the portal's own HTML. Don't extend this file with portal-specific
 * rules.
