   TD RECORDS — Sistema de estilos compartido
   V3: paleta blanco / negro / azul (el azul sustituye al dorado como
   acento). Contenido en claro, hero / menú fullscreen / footer en
   negro + azul. El menú fullscreen tiene un glow de color que
   cambia por enlace (inspirado en Reach Records).
   Ver /home/td/projects/Web Label/README.md para más contexto.
