   CS Kleen Solution — design.css
   Capa de diseño (solo estilo) que se carga después de styles.css
   y features.css. No cambia textos, precios ni datos de contacto.

   Criterios aplicados (taste-skill / redesign-skill / emil-design-eng):
   - Tipografía con carácter: Geist + Geist Mono (cifras), servidas por
     Google Fonts igual que las fuentes anteriores.
   - Un solo acento (teal de la marca); el amarillo queda como detalle.
   - Una escala de radios: contenedores 24px, piezas 14px, controles 12px,
     botones en píldora.
   - Sombras teñidas del color de fondo, no negras.
   - Menos "plantilla": fuera el subrayado ondulado repetido en cada
     título, etiquetas superiores más discretas, tarjetas solo donde
     la elevación aporta jerarquía.
   - Movimiento corto y con curva ease-out fuerte; respuesta al pulsar.
