/*
 * Respekt Gym IS — styl.
 *
 * Mobile-first doslova: tohle je rozvržení pro telefon v jedné ruce, širší
 * obrazovka jen dostane víc místa. Pravidla, která se tu drží:
 *   · cíl pro prst má aspoň 44 px a mezeru 8 px
 *   · význam nikdy nenese jen barva — vedle proužku je vždycky slovo
 *   · hlavní akce je v dosahu palce, tedy dole
 *   · focus je vidět a nic ho nepřekrývá
