/* ---------- Desktop layout override (/wth) ---------- */

/* A real two-column desktop layout, not just a wider version of the
   mobile stack: hero card + map on the left, the timeline list as a
   scrollable side panel on the right, rather than a static narrow
   column floating in empty space at desktop widths. Deliberately placed
   at the end of the file: its
   selectors have the same specificity as the base rules they override
   (e.g. .wth-timeline-list's max-height), so it has to win on source
   order — placing it earlier in the file (as a first attempt did) meant
   the later base rules silently won regardless of viewport width, only
   caught by actually screenshotting a real desktop-width render.

   The timeline column is deliberately NOT stretched to match the left
   column's exact height (e.g. via flex:1/align-items:stretch) — a first
   attempt tried that and CSS Grid's auto-row-sizing fed the list's own
   unbounded content height back into the row size, making the row (and
   the empty space under the left column) enormous, only visible once
   actually screenshotted. A fixed, generous max-height with its own
   scrollbar (align-self: start keeps it pinned to the row's top rather
   than stretched) sidesteps that circular sizing problem entirely. */
