   ECHO · HUD
   un producto de inversionesmontelongo.es

   Estetica de interfaz tactica: fondo profundo, cian sobre negro azulado,
   anillos concentricos y esquinas marcadas.

   Dos criterios que no se negocian por estetica:
   · contraste suficiente para leer de verdad (el cian puro sobre negro
     canta mucho en capturas pero cansa la vista, asi que el texto normal
     va en un gris azulado claro y el cian se reserva para acentos)
   · toda animacion se detiene con prefers-reduced-motion
