/* ========================= V20.10 NAV VIEWPORT HARD FIX ========================= */
/* Root cause of v20.9 clipping: .quick-nav inherited transform:translateY(-50%)
   from the legacy navigation rule while also being expanded to inset:0. That moved
   the entire navigation coordinate system half a viewport upward. Reset the parent
   transform and anchor both rail and panel directly to the viewport. */
