   LOOPY — LANDING — TEMA
   ==========================================================================
   Paleta rediseñada: un solo acento dominante (violeta) para todo lo
   interactivo (links, foco, CTAs), un cálido de apoyo para gradientes y
   highlights, y verde/ámbar/coral solo para estados (disponible, pendiente,
   error). El tratamiento arcoíris del logo (anteojos cian + cejas cian/rosa
   + "py" en degradé) se deja intacto — es la firma del isotipo y por eso se
   queda como el único lugar del sitio con esa paleta completa; el resto de
   la UI es deliberadamente más comedido para que el logo siga siendo lo que
   más llama la atención, no uno más entre varios elementos de colores.
