/* style.css — univerzální tmavý minimalistický motiv
   Created :: 2026-05-25
   Updated :: 2026-05-25

   TIMELINE
   2026-05-25 :: Vytvoření – globální font-size, layout LIŠTA1/2/3, breadcrumb,
                 patička, formuláře, flash hlášky, tabulky, login obrazovka, nástěnka.

   Pravidlo: font-size je definován globálně (--fs-base). Mění se jen tam,
   kde je to nutné (H1, drobné popisky), přes proměnné níže.
