   One source of truth: the site, the brand guide (/en/brand/), the brochure
   and the kit read these values. Change them here, never in a page.

   Register: the estate's portal system (UCHPE, SDUMC, AHBS), meaning square
   corners, hairlines, heavy tight Inter, mono labels and colour fields,
   expressed in NSC's own colour: the crimson of the brochure's DNA on a
   near-black wine.
