/* ==========================================================================
   KEMU — Componentes
   Tudo que `js/core/ui.js` gera: botões, cards, progresso, badges, avatares,
   toasts, modais, efeitos e gráficos.

   Mobile-first. Sem `!important`, sem cor literal — só tokens de tokens.css
   (ou `color-mix()` a partir deles). O tema escuro sai de graça.

   Sumário
