   UncleTrips — Request & offers layer (final frontend sweep)
   Customer-facing concept for supplier bidding: custom transfer quotes and
   custom / private trip requests → demo offers → accept / ask for changes /
   compare with Uncle. Builds on ui.css (panels, forms, choices, notices,
   status badges, steps). Logical properties only. No live bidding.
