/* ===================================================================
   Landing "door" — plain HTML/CSS/JS, exactly as originally authored
   (legacy-static/css/style.css), pivoted at the outer frame edge.
   Runs outside Flutter entirely so this gets real browser-native GPU
   compositing for the 3D transform instead of Skia/CanvasKit rasterizing
   it — this is why it lives here instead of in Dart.
