   PIÑA DIGITAL · Guía de alta como Agente Digitalizador

   This page's own styles. Every colour, face, shadow and radius here goes
   through a name defined in `tokens.css`; there are no literals below except
   the ones that carry no design meaning (0, 100%, transparent, currentColor)
   and one documented exception in the print block.

   That rule is what makes dark mode free: `tokens.css` redefines the values
   per theme and nothing in this file needs to know a theme exists.
