The skill doc promises shadows that shift/scale with 3D tilt; paint_box_shadow reads no rotation (paint_pass.rs:906-978) — documented lie. Either implement (offset/scale derived from rotate_x/y and perspective, ground-plane model) or strip the claim from SKILL.md + rules/depth-layering.md. Decision in the PR.
