/* Veřejné stránky hubu (/ a /cenik) — jeden soubor stylů pro obě.
   Barvy jsou tmavé tokeny z frontend-upravpdf/src/styles/main.css
   (html[data-theme='dark']): tmavé plátno, korálový akcent, jak chce rámec
   rodiny §2.6. Písmo je systémové jako v aplikacích — CSP posílá
   `font-src 'self'`, cizí webfont by se stejně nenačetl.

   nemá hash, takže změna stylů potřebuje novou hodnotu `v` v obou HTML. */
