/**
 * Evaluates one of the SDK fade curve presets for a normalized interpolation value.

 * values from timeline math or easing chains without guarding them first.
 *
 * @param curve Fade curve preset to evaluate.
 * @param interpolation Normalized progress value, typically between `0` and `1`.
 * @returns Remapped normalized value after the selected fade curve is applied.
