   Todo lo visible que comparten las aplicaciones. Nada aquí sabe de Pong ni
   de conversores: sólo de botones, campos, cabeceras y estados.

   Una regla de oro en toda la hoja: el color de acento nunca está escrito,
   siempre es var(--app-accent). Por eso la misma cabecera se ve verde menta
   en Pong y naranja en Unidades sin una línea de CSS por aplicación.
