/* Allow the page to scroll past the hero. Overrides index.css:7–17
   and the @media (max-width: 768px) html/body overflow rules in
   index.css, which locked html/body/.page to 100vh for the old
   single-screen layout.
   IMPORTANT: only html is the scroll container. Body uses overflow-x:
   clip + overflow-y: visible so position:sticky descendants
   (e.g. .dt-topbar) walk up to html for their scroll context. If body
   were also a scroll container (overflow-y: auto), sticky would attach
   to body (which never scrolls) and silently fail. We use `clip`
   instead of `hidden` for overflow-x because the CSS spec converts
   `overflow-y: visible` to `auto` whenever overflow-x is `hidden` or
   `auto` — `clip` is the only value that suppresses overflow without
   triggering that conversion. The !important is required to defeat the
   `body { overflow: hidden auto }` rule inside index.css's
   @media (max-width: 768px) block. */
