   Infomail Design System — shared components for the Claude Design restyle
   (handoff bundle). Adds ONLY the design tokens the project was missing
   (derived from the tenant brand via color-mix, so they follow branding)
   plus NEW component classes used by the redesigned pages. Existing global
   classes (.card/.badge base/.table/.toolbar/.tabs/.search) are NOT
   redefined here to avoid affecting non-redesigned pages.
