  // scrollbar and a hard-cut bottom edge in every consumer project.

  // view with `element.scrollIntoView({ block: "nearest" })`, which acts on
  // whichever ancestor actually scrolls, so moving the overflow up one level to
  // ScrollFade's viewport keeps arrow-key navigation working.
  //
  // The cap goes on the VIEWPORT, not the root: the viewport is `h-full`, and a

  // and the root would clip it with nothing to scroll.
