   as well makes <body> its own scrollport, and support.js then injects
   `html,body{height:100%}` for its standalone-canvas runtime, and the two together
   turn <body> into a fixed-height nested scroller, so the document itself is
   only ever one viewport tall. On phones that is the whole ballgame: iOS never
   collapses the URL bar, momentum/rubber-band scrolling goes, and every
   position:sticky scene resolves against a scrollport that never moves.
   Clip at the root, keep the document as the one scroller, and override the
   injected height (no !important there, so this wins). */
