Publishes decision #1's contract FIRST (before code) so D and F build
in parallel: room.browsePoints[] (0..3, deterministic per shop.seed) —
{x,z,ry,atKind,slotIndex}, same coord frame + ry convention as
counter.stand. Guarantees: walkable, reachable (door→counter flood-
fill), ≥0.6m spaced, every archetype. C adds no meshes/draws; D's rigs
ride the ≤350 interior budget. Includes the D→F→C handoff (occupancy
count → browsePoints.slice(0,min(count,3)) → one rig per point).
