What this skill does

Compare screenshots against the intended design, distinguishing approved references from historical baselines. Use for iterative implementation matching, before/after visual review, objective image telemetry, or checking a lone capture for flat, empty, or badly framed content. Judge images against the intended result. A user-approved design is the target; a historical baseline is only an earlier attempt and may be wrong. Metrics locate differences, never decide correctness.
