/* ============================================================================
   CUPHST cloud - hoja de estilos unica del panel.
   No se fragmenta en modulos: todo el lenguaje visual vive aca.

   Dos zonas cromaticas, sin mezcla:
     1. Chrome pintado en el ambar institucional --primary: SOLO la topbar y la
        barra de titulo de los modales. Sus hijos usan #fff y opacidades de
        blanco, NUNCA --text / --muted / --border: el contraste se calcula
        contra el ambar, no contra el gris.
     2. Todo lo demas -- sidebar, area de contenido (cards, tablas, inputs,
        cuerpos de modal) -- en grises oscuros. Ahi el ambar vuelve solo como
        ACENTO: boton primario, focus ring, chip activo, item de menu activo,
        valores destacados.

   Tema unico oscuro. No hay data-theme, no hay toggle, no hay modo claro.
