/* ==========================================================================
   Adventure Design – design system (veřejná část webu)
   Tokeny, typografie, layout, komponenty, navigace, patička, modály.
   Art direction: editorial automotive – Archivo v rozšířeném řezu pro
   nadpisy (druhá část nadpisu v <em> je tlumená, stejné písmo),
   ostré hrany a jemné linky místo stínů, měď jako jediný akcent.
   Stránkové styly v assets/css/<stranka>.css tyto tokeny a komponenty
   jen skládají – nové barvy/rozměry se definují zde.
   Admin má vlastní styly (admin/admin-style.css) a tento soubor nenačítá.
