How the conversion works
A direct geometric transform, so it is lossless and reversible.
Both formats are computed from a single canonical representation (CIE XYZ with a D65 white point, held in floating point) rather than by chaining one format into the next. That matters because chained conversions accumulate rounding error, and because it means a color that cannot be represented in the target format is handled deliberately rather than by accident.
When the source describes a color outside the target's gamut, chroma is reduced in OKLCh while lightness and hue are held, following the CSS Color 4 gamut mapping algorithm. Clipping each channel independently would be simpler but visibly shifts hue on saturated colors.
