   web.css — vizuální jazyk marketingového webu
   ------------------------------------------------------------
   Stejné tokeny a písma jako homepage (index.php). Homepage je
   ale scrollovaná narativa s vlastními styly uvnitř souboru;
   tohle je layout pro BĚŽNÉ stránky — poptávka, ukázky, články.

   Nahradilo Bootstrap 4/5 + FontAwesome + jQuery z původního
   webu. Žádné CDN, žádný framework: stránky jsou statický text
   a formulář, na to je celý Bootstrap zbytečná zátěž.
