/* ========================================================================
   v22 — VIEWPORT LOCK FOR PRESENTATION
   --------------------------------------------------------------------
   On a tablet-class landscape screen (iPad 11" ≈ 1180×820), lock the
   spine fly-through and the days-vs-depth race so they each occupy a
   single screen-height with no internal scroll. The whole instrument
   reads as one frame: SVG on the left, supporting data on the right,
   counter row pinned bottom (DvD) or scrubber pinned bottom (spine).

   The lock activates only at >=900px landscape, so portrait iPad and
   any phone keep the existing stacked layout. Replay/counter chips
   continue to work identically.

   We use 100svh (small viewport height) so iPadOS Safari's URL bar
   doesn't push content off-screen during scroll. Falls back to 100vh.
