/*
 * widget.css - vzhľad chatovacieho okna.
 *
 * Beží na cudzích weboch, preto má všetko predponu `cb-` a vlastné
 * hodnoty farieb aj písma: nič si neberie zo štýlov hostiteľskej
 * stránky a nič jej nepokazí.
 *
 * Farbu si okno berie z premennej `--cb-primary`, ktorú nastavuje
 * skript podľa chatbota. Tmavú tému má len okno vložené priamo do
 * stránky (`cb-root--auto`) - na webe zákazníka je vždy svetlé, aby sa
 * vzhľad nemenil pod rukami.
