Use when the user wants to create, edit, or inspect an architectural floor plan / building layout as code — e.g. "draw a 2-bedroom apartment", "add a bathroom to this plan", "make the bedroom 1 m wider", "lay out an office floor". ArchLang is a tiny text language that compiles a .arch file to a professional floor-plan drawing (SVG/PNG/PDF/DXF). Drive it entirely through the `archlang` CLI; do not hand-render.
