Description: Generates sequential, diverging and categorical colour
        palettes from a single seed colour in OKLCH with CIEDE2000
        spacing, and audits every palette under simulated colour-vision
        deficiency, greyscale conversion, sRGB gamut and WCAG contrast.
        Colour-vision deficiency is simulated at severity 1.0 with the
        model of Machado, Oliveira and Fernandes (2009)
        <doi:10.1109/TVCG.2009.113>; the design rationale follows
        Crameri, Shephard and Heron (2020)
        <doi:10.1038/s41467-020-19160-7>. Mirrors the 'Python'
        reference implementation maintained in the same repository and
        is validated against shared parity fixtures. Thresholds are
        configurable design rules, not established accessibility
        cut-offs.
