   Se carga DESPUÉS de styles.css y solo añade componentes nuevos.
   No redefine ningún token de marca: navy/azul siguen mandando.

   Verde circular (nuevo, único token añadido):
     --circ       #0E7C5A  → 5,19:1 con texto blanco  (AA ✔, mismo nivel que --accent 5,00:1)
     --circ-deep  #0B6B4A  → 6,53:1 sobre fondo blanco (texto)
   El ámbar de datos (#C2610A) da 4,19:1 con blanco → NUNCA como fondo de botón,
   solo como trazo/borde de dato.
