review-node
Review a shader node by id/name with an end-user lens—discoverability, mental model, parameter clarity (including short parameter/group/layout labels so the node body grid does not break), panel/canvas flows, help text, and layout vs docs/user-goals. Reply with a 1–2 sentence evaluation and a bulleted list of recommended changes (or None). Use when the operator runs `/review-node` or asks for a structured node QA pass with a node identifier.
