/* ============================================================================
   MEGA MENU 01 - CLASSIC PRACTICE PANEL  (drop-in dental header component)
   Light full-width panel, three service-group columns, featured offer card
   with a photo, bottom strip with hours + phone + Book.
   Header behaviour: headroom (hides on scroll down, returns on scroll up,
   compacts when stuck). Switch with --mm-header-mode: pinned.

   Restyle by overriding tokens only. Nothing below :root is hard-coded.
