/* ===========================================================================
   Acquisition Radar, spoločný dizajnový systém.

   Vizuálna predloha je yorby.ai (Šimonov výber). Čo som z nej prebral:
     - Montserrat na všetko, nadpisy semibold s tesným prestrkom
     - biela plocha, takmer čierne písmo, jemné sivé linky (shadcn tokeny)
     - obrovský centrovaný hero nadpis, line-height pod 1
     - tlačidlá: plné čierne so zaoblením 1rem, druhotné ako pilulka
     - karty rounded-3xl, tenký rám, mäkký tieň, na tmavej téme biela 4 %
     - radiálne žiary na pozadí sekcií namiesto plných farieb
     - sekcie max 1200 px, veľké vertikálne medzery, vstup animáciou zdola

   Čo som NEPREBRAL a prečo: yorby má stenu referencií a ceny konkurencie.
   My zákazníkov zatiaľ nemáme, takže by to boli vymyslené tvrdenia.
   Namiesto toho sú na tých miestach reálne čísla z nášho indexu.

   Tento súbor používajú index.html aj app.html. Jedna téma, dve stránky.
