/* ============================================================================
   MEGA MENU 02 - SPLIT PANEL WITH A LIVE RIGHT SIDE
   Left rail of treatment groups. Hovering or focusing a group swaps the right
   side: the group's treatments with illustrative prices, a photo, and one line
   saying who it is for. Arrow keys move between groups.
   Header behaviour: headroom (hides on scroll down, returns on scroll up).
   Switch with --mm-header-mode: pinned.
   Restyle by overriding tokens only.
