   KC UI — capa de diseño común de KC Systems
   ────────────────────────────────────────────────────────────────────
   Se carga DESPUÉS del <style> de cada pantalla y le gana por orden y
   especificidad (html[data-theme]). Las pantallas siguen escribiendo sus
   variables de siempre (--text, --surface, --gold, --text-3...): acá se
   redefinen todas, así que la lógica de cada plantilla no se toca.

   Regla de animación: solo transform y opacity, 150–300 ms en UI,
   y nada se mueve con prefers-reduced-motion.
