A woven fabric texture, warped into the area you mark, with parametric Korean pleats (pressed creases, heading tape, pleat tips), soft edges, a floor shadow and an optional concealed-track top. Runs entirely on this device — your photo never leaves the browser. Only the fabric changes; everything around it stays as photographed. The install choices (inside / wall, per-window / one piece, sheer / opaque), the default-correction prompt and Continue editing all drive this local composite and are written into the export JSON.
