   HOOK ENGINE - Martín Rey
   Herramienta gratuita. Mobile first. Tema dark único.

   De la marca de Martín se toman solo colores y tipografías.
   Todo lo demás (radios, espaciados, componentes y motion) es
   propio de esta herramienta.

   Radios: bloques 16-20px, tarjetas 14px, controles 10px,
   chips y botones principales en píldora.
   Un solo acento: el turquesa. #ff8080 solo para errores de
   formulario, igual que en el formulario de martin-rey.com.
