 * Hand-written, no framework, no build step. Colours come from custom properties so
 * the accent is a single value the admin UI can change, and both themes are defined
 * up front: the visitor's system preference decides, and an explicit choice is
 * stamped onto the root element as data-theme.
 *
 * The font stack is deliberately the system one. It renders Cyrillic, Latin and CJK
 * from fonts the device already has, which means nothing to download and no locale
 * that silently falls back to something ugly.
