/* The two overflow-x declarations are deliberate — do NOT collapse them.
   Several chrome elements bleed past the viewport by design (.ambient, the
   .dd-panel dropdowns, the off-screen .skip-link), so the horizontal axis
   must be suppressed. But overflow-x:hidden forces the OTHER axis to compute
   as overflow-y:auto, which makes html/body a scroll container and silently
   kills position:sticky everywhere on the site (measured: a sticky strip sat
   at -691px instead of 0). overflow-x:clip suppresses the same overflow
   WITHOUT creating a scroll container, so overflow-y stays visible and sticky
   works. hidden stays first as the fallback for engines predating clip
   (Chrome <90 / Firefox <81 / Safari <16), which ignore the second
   declaration and keep the old behaviour exactly. */
