Draft — Unreleased:This page is in active development. APIs, class names, and behavior may change before the release is finalized. Use it as a preview of what's coming — not as a stable integration target.

Scene-free terrain placement service. Extracted from PlacementSystem to make the terrain paint path directly unit-testable. Handles terrain-name → TileSet-ID resolution, plan building/gating, plan application, and signal emission (pre_terrain_paint, success/failed). Usage: var service := TerrainPlacementService2D.new() service.configure(building_state, building_settings) var report := service.try_place_terrain_by_name(&"dungeon_floor", cell, map, owner)
