/* Klienti — klinická paleta pro psychologickou praxi.
   Chladné neutrály, bílé karty oddělené stínem místo barvy, tlumená modrá
   jako jediný akcent. Barevné jsou jen stavy termínů — nic jiného, aby
   naléhavost byla vidět na první pohled.

   Kontrasty: všechny dvojice text/podklad splňují WCAG 2.1 AA (4,5:1),
   ověřeno měřením. Barva nikdy nenese informaci sama — u každého stavu je
   i slovo a počet dní. */
