flatten_tshirt — bimanual t-shirt flattening
A dual-arm Piper flattens a crumpled t-shirt on a table. Success combines a coverage signal (catches 'still crumpled') with a shape-distance signal against a canonical flat pose (catches 'spread out but still folded').
Part of a bimanual deformable-object (cloth / bag) manipulation benchmark. Physics is a GPU cloth solver co-simulated with the robot in a single model; observations are rendered with a photorealistic renderer.
