Clearing small obstacles from Ember Reach

An initial cleanup in four Ember Reach rooms removes small rocks, fallen logs and incidental low props from walking and dodge routes. Larger terrain, native vents and braziers, lamps, clues and breakable supplies remain. The wider biome rollout is still awaiting checks. The image comes from development testing with enemies suppressed; controller, complete-biome and packaged-build testing remain pending. This is a development checkpoint, rather than a new game release.
