A control's range is a claim about its input

valueRange is not a styling choice. It is an assertion that every value the control will ever be handed lies inside it — and the control is handed values by import, restore, migration and the previous version of your own code, not only by the user's finger.

/**
 * Deeper than the ±12 dB the bands span, because an imported profile's own trim is computed from
 * the summed response rather than from its tallest band, and so goes past −12: the lowest across a
 * sample of sixty published profiles was −12.1 dB.
