/*
 * Download pages (/f/<code> file + folder), the password page and the
 * 403/404 pages — redesign 2026-10-13, ported from
 * docs/design/2026-10-13-file-host/styles.css ("DOWNLOAD PAGE (one-screen)",
 * "file stack", "right column content" and the 900/760 px breakpoints).
 *
 * Dark is the default; light follows prefers-color-scheme. Each category
 * theme sets --accent / --accent-ink on <html> (get-file/*.blade.php);
 * text that sits on the accent always uses --accent-ink. Text never sits on
 * the accent blobs in a colour lighter than --ink-2.
 *
 * Every font is served from this site (public/fonts, the latin subsets of
 * the SPA's @fontsource-variable packages; SIL Open Font License).
