   Extinsys — landing · estilo NEUMORPHISM

   Ojo: esto ya NO es el design system Modernist de la app (frontend/src/index.css),
   que es plano, de radio 0 y divisores duros de 2px. Acá las superficies son
   extruidas: fondo monocromo de medio tono y doble sombra (una luz arriba-izquierda,
   una sombra abajo-derecha) para que cada bloque parezca levantado o hundido.

   Lo que se conserva del sistema viejo: el acento #ec3013, la tipografía Archivo
   y el vocabulario de clases. Lo que cambia: radios, sombras, fondos y la forma
   de separar celdas (antes bordes, ahora aire entre tarjetas levantadas).

   Reglas que hacen que esto no se rompa:
   - El fondo NO puede ser blanco puro ni negro puro: sin medio tono no hay relieve.
   - El relieve va en las superficies, nunca en el texto. El texto mantiene
     contraste alto (el punto flojo conocido de este estilo es la legibilidad).

   Documento legal — /terminos, /privacidad, /datos

   Es la misma paleta y la misma tipografía que el resto, pero con dos diferencias
   deliberadas frente a las secciones de venta:

   - NADA de reveals ni de contadores. Un texto legal que aparece de a poco al
     hacer scroll es un texto que, buscado con Ctrl+F, puede estar invisible en el
     momento en que se lo lee. Acá el HTML se sirve completo y quieto.
   - El relieve baja de intensidad. Las piezas levantadas son el índice y los
     recuadros; el articulado va sobre el fondo, sin caja, porque una columna de
     tarjetas apiladas rompe la lectura corrida de un contrato.

   Tampoco hay selector de tema: es un documento con valor jurídico, tiene que
   verse igual en toda pantalla y salir igual impreso.
