/* Never allow the page itself to scroll sideways.
   `overflow-x: clip` (not `hidden`) is used deliberately: per the CSS spec,
   whenever overflow-x and overflow-y differ and either one is "hidden"
   (or auto/scroll), the browser silently forces the other axis to "auto" as
   well — turning html/body into their own scroll containers and breaking
   `position: sticky` on .canvas-outer (the schema stopped staying fixed
   while scrolling). "clip" is exempt from that rule, so it blocks sideways
   overflow without hijacking vertical scrolling. */
