/* Tokeni dizajna: JEDINO mesto za boje, fontove, razmake, zaobljenja i senke.
   Brend menja izgled samo ovde. Ostali CSS koristi isključivo ove promenljive.
   Raspored po uzoru na irist.com, sopstvena paleta (tirkizna) i pravougaone forme.

   VIŠE BRENDOVA: tema brenda (/theme/theme.css, primer: css/tema-proba.css) učitava se posle ovog fajla
   i menja SAMO "boje brenda", i to za svetlu i za tamnu temu (isti obrazac kao blokovi na dnu fajla):
     --color-primary, --color-primary-hover, --color-primary-soft, --color-primary-border,
     --color-on-primary, --color-accent, --color-focus-ring
   Po želji još: --font-sans (font kao fajl u temi; spoljni fontovi i CDN su zabranjeni),
   --radius-* i --shadow-primary. Neutralne boje (tekst, podloge, okviri) i značenja (success, warn,
   danger) su zajedničke za sve brendove, da npr. crveno svuda znači opasnost.
   Kontrast (WCAG AA, bar 4,5:1) u obe teme: --color-on-primary na --color-primary, i --color-primary
   na --color-bg, --color-surface i --color-primary-soft. */
