   Default scrollbars are a light-grey chrome widget that sits badly on a dark

   Two mechanisms, both needed:
     * scrollbar-width / scrollbar-color — the standard, Firefox and modern
       Chromium. Only accepts a thumb and track colour, nothing else.
     * ::-webkit-scrollbar-* — Chromium and Safari, where the finer control is.
   Colours come from existing theme variables, with literal fallbacks so this
   block still works when pasted into a page that has no token layer.

   Scroll containers also get overscroll-behavior so a table that reaches its
   end stops rather than scrolling the page behind it, and a momentum flag for
   iOS. */
