/* The portal's shared stylesheet (D1): the tokens, the base elements, and the pages of index.html and
 * meeting.html. Both pages load it by its absolute path (/m/<slug> resolves relative URLs to meeting.html).
 * meeting.css (injected by meeting.js, after this file) holds only the in-call overlay, so it wins every tie.
 *
 * Rules that bind this file (app/portal/README.md, "Styles and tokens"):
 *  - the tokens live in the block below, light by default, dark under the OS preference and under
 *    [data-theme="dark"]; data-theme="light" forces light on a dark OS; --accent is set by theme.js (branding)
 *    and is never redefined here, so fills use --accent and text, borders and rings use --accent-text;
 *  - no hex colour outside the token block, no external origin, no stylesheet import, no font-face rule, no web font;
 *  - a rule that belongs to one page is scoped (#gate, #view-home, header .bar ...): never a bare .actions,
 *    .bar, .state or .when. */
