/*
 * UnoChat design tokens — shared by marketing site, admin panel and docs.
 * Two themes on one set of component styles: dark (default) and light.
 * Cyrillic note: Plus Jakarta Sans has no basic Cyrillic glyphs (Google's
 * own build only ships a "cyrillic-ext" subset covering historic ranges),
 * so the body stack falls back to the OS UI font for ru/pl/de text —
 * JetBrains Mono does carry full Cyrillic, so labels stay on-brand.
