/* ============================================================
   ÚVODNÍ STRÁNKA (public/landing.html) — VZHLED B „TMAVÝ VELÍN“

   - Barvy, písmo, zaoblení a stíny jen přes var(--nvk-…) z tokens.css.
   - Stránka je statická; tenhle soubor jí servíruje doplněk
     nvkStylesForLanding ve vite.config.ts (/nvk/landing.css).
   - Názvy tříd odpovídají HTML a skriptům stránky — při úpravě
     přejmenování hlídat i JS dole v landing.html.
   - Velikosti nadpisů jsou „marketingové“ (větší než v aplikaci),
     proto jsou zapsané tady a ne v tokens.css.
