   founding.css — /founding (TERM-8). Miembros fundadores y la reserva.

   Movil primero: a 390 px todo va en una columna y nada desborda (los
   campos y las tarjetas son width:100% con box-sizing). Desde 860 px las
   tres tarjetas se ponen en fila.

   NI UN #RRGGBB: todo var(--sn-*) de public/css/brand.css. Un solo acento
   (cian), Manrope en el texto y mono en las etiquetas.
