   Todos los colores derivan de 5 variables que vienen de Ajustes de Tienda:
     --rs-primary   (color_principal)
     --rs-accent    (color_botones)
     --rs-agotado / --rs-promo / --rs-descuento  (colores de etiqueta)
   El resto (tintes, hovers, bordes) se calcula con color-mix(), así que
   cambiar la paleta en el panel re-tematiza toda la home.
