   MTC Tennis — Layout Utilities
   Phase 1A: Namespaced layout classes only. No visual changes to the site.

   All classes use the .mtc- prefix to avoid collisions with existing
   Bootstrap or custom selectors. None of these classes are referenced
   by current markup — they are ready for Phase 2 migration.
