/* ============================================================
   19-firstvisit — "Your First Visit, Minute by Minute" timeline.
   All selectors scoped under .sec-19-firstvisit.

   Design decision: section background is a flat var(--bone-2) band
   (not --white) — the spec's own type/color rules forbid flat white
   cards on a white section, and this section's cards are white.
   A subtly deeper bone tone + hairline top/bottom borders let it read
   as its own moment between 08-why and 09-team without breaking the
   "never a flat endless scroll" rhythm or the no-flat-white-on-white rule.
