  Maximus on the web. Every page in invite-site/ links this file and declares no
  colours or font stacks of its own (lib/__tests__/webBrand.test.ts checks).

  Sources: docs/DESIGN_TOKENS.md, assets/brand/README.md, lib/theme.ts.
  Two typefaces: Unbounded (display) and Manrope (reading). Each page loads both
  from Google Fonts: weights Unbounded 600/700/800, Manrope 400/500/600/700/800.
