   Basecamp Commerce — main stylesheet
   Ported from the "Basecamp Commerce Website Redesign" design handoff.
   Two intentional departures from the base brand tokens (per the handoff):
   rounded pill buttons / 24-32px card radii, and translucent card surfaces
   that let the animated topo background read through.
