 *
 * Plain CSS, served as a file rather than inlined in view.php: the page text
 * then starts near the top of the HTML instead of behind 17 kB of styles, and
 * the browser caches it once for the whole portal.
 *
 * Not built by Vite on purpose: the build empties htdocs/assets/, and this
 * sheet must survive a portal running on the CDN fallback.
 *
 * Surfaces, borders and text follow the DaisyUI theme variables (--b1, --b2,
 * --b3, --bc), so a per-instance theme repaints the content along with the rest
 * of the page and the dark variant needs no separate rules. What is specific to
 * a document and has no theme token of its own is declared below as a --mmd-*
 * variable, with the value the portal has always used; data/theme/theme.css
 * overrides those it wants. Every oklch(var(...)) carries a literal fallback, so
 * the sheet still renders if the theme stylesheet fails to load.
