/* Capa de refinamiento visual encima de app.css (que define la identidad:
   verde registro + laton, Inter + JetBrains Mono). Este archivo no cambia
   la identidad, la vuelve mas sobria y minimalista:

   - Neutros mas calmos (piedra calida en claro, grafito verdoso en oscuro)
     y superficies separadas del fondo por sombra muy suave + borde fino,
     en vez de bordes marcados en todos lados.
   - Tablas, formularios, botones, badges, dropdowns y modales con el mismo
     radio, el mismo ritmo de espaciado y transiciones cortas (120-220ms).
   - Micro-animaciones de entrada solo en lo que se visita seguido
     (contenido del panel, filas de listados, dropdowns), siempre cortas.
   - Skeletons (`.sk-*`) para todo lo que espera la red: navegacion entre
     pantallas, notificaciones, busqueda del POS (ver assets/js/skeletons.js).

   Todo queda cubierto por el apagado de animaciones de app.css
   (prefers-reduced-motion y html.reduce-motion). */
