/* =========================================================================
   forestana.com — 3D atlas hero
   A stack of cartographic plates (satellite, hydrography, parcels, indigenous
   lands) suspended in CSS-3D space, like vellum overlays on a drawing table.
   A figure-eight camera orbits the stack; a light sweep rakes the right edge;
   the middle plates flutter softly; dust drifts at different depths.
   Motion is driven by assets/js/hero-atlas.js. Static + reduced-motion safe.
