Class: FurnitureItem

Structural furniture: chairs, tables, beds, wardrobes, shelving. COICOP 05.1 (furniture and furnishings). Grounded in Product Types Ontology:

http://www.productontology.org/id/Furniture

Assessment: FurnitureAssessmentEnum (structured structural assessment). Structural soundness is the primary redistribution signal for furniture — a scratched but solid chair is redistributable; a wobbly but clean one is not. assessment_result required regardless of usage because new flatpack furniture can have manufacturing defects or assembly issues.
