/* ==========================================================================
   History — masonry timeline (history.html only)
   Rebuilt 2026-08-11: two independent flowing stacks either side of a
   centre spine. Each side just stacks its own cards with a tight, uniform
   gap — no row-based alignment, no reserving height for the opposite side.
   Deliberately uses its own .htl-* namespace — see prior note: inheriting
   the legacy .timeline classes would mean an override war with ~30
   !important rules in density-review.css / modern-refresh.css.
