    UnclassedColorsRenderer is the per-feature sibling of
    GraduatedRenderer that skips the IntervalBinner entirely:
    instead of bucketing the attribute value into N classes, it
    normalises the value linearly into [0, 1] over the ramp's
    (minValue, maxValue) and samples the ramp directly.

    Use case: 2D depth fields, continuous flow rates, anywhere the
    user wants smooth colour transitions instead of stepped bins.
    Equivalent to QGIS / ArcGIS Pro's "Unclassed Colors" /
    "Continuous" symbology.

    Below-min values use \ref belowRangeColor (default = the ramp's
    start color); above-max values use \ref aboveRangeColor
    (default = the ramp's end color). NaN / invalid attribute
    values fall back to \ref noDataColor.
