  /* Height is a percentage of the hero (78%) so the backdrop genuinely spans
     down behind the VSL and signup card. Width stays capped (not bare 100%)
     so height — always ~1300-1700px at 78% of a stacked hero — permanently
     dominates the `slice` scale over width. That's the structural fix for the
     original ultrawide bug: since height always drives the scale, the
     artwork's full vertical extent (including the peak node near the top) is
     always in frame; only the horizontal extremes bleed off the sides, which
     reads as intentional at this opacity, not a defect. The area-fill
     gradient already fades to transparent toward the artwork's own bottom
     edge, so the extra height reveals that built-in fade rather than a hard
     crop. 3600px covers every mainstream monitor (1920/2560/3440/3840) with
     real margin — verified the top node stays in-frame up to ~4200px, only
     clipping past ~4500px, well beyond any realistic single browser window. */
