   MLAutomation.ai — shared design system
   Single source of truth for the public/brand surface and shared chrome.
   Layered on top of Bootstrap 5.3. Documented in /DESIGN.md.

   Token layers:  primitive  →  semantic  →  component
   Legacy aliases (--brand, --accent, --surface, --card-border, ...) are kept
   so the large body of existing inline template styles keeps working.
