/* =========================================================
   Desktop ~5% down-scale (mimics browser zoom 95%)
   Applies from 1024px upward with NO upper limit, so every
   desktop width (incl. 1920px) reads like browser zoom ~95%.
   Mobile/tablet (<1024px) stays pixel-identical: nothing here
   leaks below the breakpoint. We scale px values (and vw ends
   of clamps) by 0.95 instead of using CSS `zoom`: `zoom`
   shifts getBoundingClientRect/scroll math and breaks the GSAP
   ScrollTrigger pins (story/apply/tear/geo) and Lenis — it
   leaves a ~5% gap on pinned sections and a snap at pin
   release. Scaling px keeps vh/100vh/scroll untouched, so every
   scroll-driven animation behaves exactly as before. vh ends of
   clamps are deliberately left unscaled (viewport-relative).
