Streaming normalization — estimated gain change

Important: normalization systems change over time and some platforms do not publish a fixed music target. The cards below distinguish published targets from engineering/reference estimates. A positive number means the service would need to turn the track up to the reference level; a negative number means it would turn it down. This is gain compensation only — it does not model each service’s limiter, codec, album normalization, or playback mode.
