   HERO 3D — keep the WebGL canvas from "blowing out" the grid
   track on narrow screens. A grid item defaults to min-width:auto,
   so the canvas's intrinsic pixel width (~670px) forces the hero
   column wider than a phone screen — which pushed the 3D model
   off-screen and shifted the absolutely-positioned "Scroll" cue
   (left:50%) off-center. min-width:0 lets the track size to the
   viewport instead; hero3d.js's ResizeObserver then fits the
   canvas to it.
