/* ── STICKY INVARIANT ────────────────────────────────────────
   The nav (.nv) uses `position: sticky`. For it to stick to the
   viewport, NO ancestor may have overflow:hidden|auto|scroll|clip

   perspective/will-change:transform (those create containing blocks
   that capture the sticky). Use `overflow-x: clip` (NOT hidden) on
   body — `clip` doesn't create a scroll container.
