/* Safety net — kill any horizontal page scroll that a future change might
   cause. Uses clip (not hidden): clip does NOT create a scroll container,
   so position: sticky descendants (docs TOC) keep working against the
   viewport. hidden would compute overflow-y to auto, turning body into a
   scrollport and silently breaking sticky. The hidden line above clip is a
   fallback for browsers without clip support (pre-2021). */
