 * (the window does), the sticky nav had zero scroll range and rode the page
 * down. `overflow-x:clip` keeps the horizontal clipping without creating a
 * scroll container, so the sidebar can stick. (`clip` is exempt from the rule
 * that forces the other axis to `auto`, so overflow-y stays truly visible.)
