/* ==========================================================================
   ProFabrik web 2026, hlavní stránka a podstránky (vzhled podle návrhu z Claude Design)
   Barvy z loga: amber #FCA424 + břidlicová. Písmo Saira, nadpisy v zúžené šíři.
   Zaoblení: ovládací prvky 6 px, karty a fotky 8 px.
   Vrstvy (z-index): hlavička 50, lišta cookies 90, skip link 120.
   Web je vždy světlý, systémový tmavý režim nesleduje. Sekce se pravidelně střídají
   bílá a světle šedá, tmavě modrá je jen karta poptávky a patička na konci.
