   This file is the SINGLE SOURCE OF TRUTH for the brand.
   The :root block below is the design-token layer. The future
   Next.js + Tailwind webshop should mirror these exact values
   (e.g. in tailwind.config theme.extend). Keep it clean.
   Page-specific styleguide CSS lives further down, clearly separated.
