   REX.digital — huisstijl
   ----------------------------------------------------------------------------
   Kant-en-klare stylesheet, identiek aan rexdigital.nl.
   Geen bouwstap nodig: inladen met één <link> en klaar.

       <link rel="stylesheet" href="/rex-brand.css">

   Deze regel moet ALS LAATSTE stylesheet staan, zodat hij oude stijlen
   overschrijft.

   Alle kleuren staan als RGB-kanalen in :root. Wil je later één kleur
   aanpassen, dan doe je dat hier en verandert het overal mee.
