/*
  The brand's foundation, shared by the fan app and the clubs' back office: tokens, base styles,
  type, buttons, chips, cards, notes and form fields. Each app adds its own sheet on top (fan.css,
  staff.css) for what only it has.

  Tokens are the brand guide's (docs/brand-guide.md, §3) and nothing else. The scanner's status
  colours are not here and must never be: BrandRulesTests fails the build if they appear outside the
  scanner. Class names start with f- for "foundation".
