/* Weightlifting Yearbook 1983 — English summaries.
   Mobile-first: the base rules target phones; min-width queries only add room on
   larger screens. Touch targets are at least 44px; wide tables scroll inside their
   own box (with edge shadows as a scroll hint) so the page never scrolls sideways. */
