layout.js placeBrowsePoints(): 1–3 deterministic floor poses in front of
browsable floor fittings, facing the goods. Guarantees (all asserted):
walkable (occ-free, not reserved), reachable from spawn (door→counter
flood-fill), ≥0.6m apart + clear of keeper stand, every archetype (rich
candidate ring — 4 sides×2 gaps + diagonals — plus a nearest-free-cell
fallback so tight/mismatched rooms still yield ≥1). Pure data: no meshes,
no draws; ≤350 law untouched. Exposed as room.browsePoints[]
{x,z,ry,atKind,slotIndex}, same coord frame + ry convention as
counter.stand (contract in LANE_C_NOTES).
Validated headless: 180 type×archetype×seed combos → 0 empties (177×3,
3×1 via fallback), determinism 0 fails, min-sep 0.7m, 0 keeper clashes.
Test page: cyan browse-post markers on the 'path' overlay + HUD count.
