   Why `clip` over `hidden`: `overflow-x: hidden` on html/body creates a scroll
   container that breaks position:sticky for .landing-header on some browsers

   a scroll container, so sticky keeps tracking the viewport.
   Why both html AND body: iOS Safari ignores body-only `overflow-x: hidden`
   during touch swipe; the viewport (html) can still rubber-band/drag laterally.
