/* ══════════════════════════════════════════════════════════════
   KACHAI · Dialog System
   Sustituye confirm()/alert() nativos por una superficie propia de la
   marca. Usa la capa semántica de kachai-tokens.css, por lo que se
   adapta solo a dark/light. El botón de confirmación usa el acento
   violeta/índigo aprobado (--dialog-accent), acotado a esta UX.
