   ║  Section 1 (ROOT TOKEN BRIDGE) is a migration shim.     ║
   ║  It exists to prevent UI breakage while legacy token     ║

   ║  canonical var(--mr-*) tokens page by page.              ║

   ║  • DO NOT rely on these tokens in new code.              ║
   ║  • Every new line of CSS/HTML/JS must use var(--mr-*).   ║
   ║  • This entire section will be deleted after PR-308-I.  ║
