/*
 * eventnotes-site — site.css
 * T-269. Own layout — NOT a copy of eventnotes-app's or eventnotes-admin's
 * styling (AC-8). Every color and corner-radius value below is copied
 * LITERALLY from product/design/tokens.css (Sakura palette, Д-020) — only
 * the roles this site actually needs, not the full token set (no dark
 * theme, no premium/dev-badge roles: this site has none of those surfaces).
 * check.sh (CH-5) greps each literal against tokens.css on every run — do
 * not introduce a color or radius that isn't copied from there.
 * Font: system stack from tokens.css — no @font-face, no remote font.
