    container: HTMLElement
    label: string
    min: number
    max: number
    step: number
    initialValue: number
    scale?: SliderScale

    Value scale. log requires min > 0 (position 0 still yields exactly 0, so a κ=0 "no absorption" setting stays reachable) and ignores step, which is fixed to the normalised track resolution.

    format?: (value: number) => string

    Format the readout text. Defaults to value.toFixed(2).

    constrain?: (value: number) => number

    Constrain the parsed value before invoking onChange.

    rangeForValue?: (value: number) => { min: number; max: number }

    Derive value-space bounds after exact entry widens a specialised track.

    onChange: (value: number) => void

    Fired with the constrained value on each input event.
