/* ============================================================
   POLAND STREET — Real Assets | Structured Capital
   Motion Edition — "The Seam"
   ------------------------------------------------------------
   One bronze element threads the page: born in the load
   sequence, fluid in the hero, a scrubbed thread through the
   positioning and focus acts, strata in the capital stack,
   light through London's arteries, an arc to the world,
   a resting point in the footer.
   ------------------------------------------------------------
   Progressive enhancement contract:
   - No JS / reduced motion / no WebGL → the page reads as the
     static v1 experience. Nothing is hidden unless the motion
     system has actually armed itself (html.motion.armed).
