/* =============================================================
   SUPER DIGITAL TOOLS — hoja de estilos única de todo el sitio.

   Un solo archivo para todas las páginas: se descarga una vez y se
   reutiliza al pasar de una herramienta a otra.

   El color de cada herramienta se aplica con un atributo en la
   etiqueta <html>:
     <html data-tool="email">    → calculadora de email marketing
     <html data-tool="ingles">   → test de nivel de inglés
     (sin atributo)              → color de la casa, para la portada
   Los neutros, la tipografía, las sombras y los componentes son
   los mismos en todo el sitio.
