   Light / editorial: off-white canvas, bright-cyan blocks, serif display,
   monospace technical labels. Sourced from the 2026 brand deck.

   Linked via {% static 'css/public-brand.css' %} from base_public.html.
   A linked stylesheet needs NO CSP nonce (only inline <style> blocks do).

   Tokens are CSS custom properties — to match the deck's exact serif/cyan,
   change the single variable here and every page follows.
