   navrhniweb.cz — design v8 „cinematic studio"
   Celotmavý kinematický vzhled: WebGL aurora v hero (s CSS fallbackem),
   sklo, gradientová typografie Sora, mikrointerakce.
   Paleta zůstává: indigo #4f46e5 → modrá #2563eb → cyan #06b6d4.

   DŮLEŽITÉ: veškeré schovávání obsahu (reveal animace, slovní nástupy)
   je podmíněné třídou .js na <html>, kterou přidává PRVNÍ řádek main.js.
   Bez JS je celý obsah normálně viditelný.
