/* russ.onl — one page, one purpose. The palette, type and corners are
 * Mietblick's (verwalteros/public/styles.css): deep navy for headings, fresh
 * green for the one positive action, warm cream as the canvas, charcoal for
 * body text, Figtree, one 8px corner. What is different is the pace: a
 * landing page, so the space between things is generous on purpose.
 *
 * Fonts are self-hosted (SIL OFL, licences in /fonts) — no font CDN, so no
 * visitor IP goes to a third party on page load. Figtree has no Cyrillic, so
 * the Russian page falls through to the system sans for those glyphs; the
 * unicode-range keeps that switch per character. */
