/* =====================================================================
   ALSflow — stránka AI asistentů

   Navazuje na site-pages.css + flash.css. Odsud jsou jenom součástky,
   které jinde na webu nejsou: interaktivní ukázky, ceníkové karty
   a chat vpravo dole.

   Stará verze téhle stránky měla vlastní designový systém — 55 kB
   stylů v hlavičce, vlastní barvy, vlastní tlačítka, vlastní patičku.
   Vypadala jako web jiné firmy. Tenhle soubor je z ní to, co za
   přenesení stálo, přepsané do tokenů zbytku webu.
