   Summr Design — landing pública.

   Paleta oceánica de la marca llevada a su versión luminosa: base casi negra
   con matiz cian y acentos saturados (aqua → cian → marea) que son lo único
   brillante de la página. El mark del producto es una masa oscura: sobre
   fondo oscuro va la versión reversa y sobre papel la positiva.

   El movimiento es funcional: entradas al hacer scroll, respuesta al hover y
   una aurora lenta de fondo. Todo con transform/opacity (GPU) y todo se apaga
   con `prefers-reduced-motion`.
