## Drawn and procedural media

The configurator's front elevation and plan, the seat-module cutaway, the plans, the door and lift drawings, the wall
elevation, the leg profiles and the Martindale figure are drawn in code (SVG / canvas) for this site. The drawings
fill upholstery with the Poly Haven fabric textures above, at each texture's real-world size.
