/* Stravník — jeden štýl pre web aj portál (bez build kroku)
   Farby podľa toho, ako pôsobia na ľudí pri jedle:
   · paprika #e0562b — teplá červeno-oranžová: povzbudzuje chuť a vyzýva k akcii (tlačidlá, značka)
   · bazalka #2e8b57 — zelená: čerstvosť, zdravie, dôvera (peniaze, potvrdenia, „hotové")
   · krémová #fbf7f0 — teplý podklad ako chlieb a obrus; bez studenej bielej
   · uhoľ #24211c — text, nie čierna: mäkšie a čitateľnejšie
   · modrá len na informácie (stavy, odkazy) — modrá potláča chuť, preto nikdy ako hlavná */
