   authored against Calcite can drop this file in and Just Work.)

   Brand layer: High Street (Strong Blue / Medium Blue / Gold / Ice Blue)
   per Branding Guide 2025. Red is reserved for the logo only and is NOT
   available as a UI token.

   Font substitution: High Street specifies Tenorite (Microsoft cloud font,
   not openly redistributable). For previews we load Source Sans 3 from
   Google Fonts as the nearest match. The --calcite-font-family stack keeps
   Tenorite first, so licensed users get the real thing automatically.
