Author physical road furniture, layered terrain and atmosphere, projected illuminated route signs, and detailed Blender coachwork. Refine camera mass, wheel contact, chapter composition, and compact reading space while preserving approved content and audio contracts. Include isolated Blender source, before/after and hardware Chrome motion evidence, preservation hashes, validated preview checks, and documented inherited unit failures.
