/* Словолов — shared foundation for every public page.
 *
 * «Чорнило на теплому папері»: one ink diluted four times on aged paper, one
 * sealing-wax accent that is an action, never decoration. Tokens mirror the
 * app's design_tokens.dart via the brandbook (admin SPA → «Брендбук»); the
 * palette test chain in admin-ui keeps those values honest, and this file
 * quotes them.
 *
 * Self-hosted everything: the two variable fonts live in /assets/fonts and are
 * the ONLY non-page requests this site makes. No CDN, no analytics, no
 * external image — the offline-first charter applies to the site too.
