/* =====================================================
   MH Theme — Motion System
   Phase 9: controlled reveal presets + reduced-motion safety

   Motion rule: no animation ships unless it helps guide attention,
   sequence information, reduce overload, show interactivity, or create a
   controlled premium perception. This layer centralizes reveal behavior so
   old .mht-* sections and new .mht-* components use the same motion contract.
