    doc = """ColorChecker Classic 24-patch color chart in ACEScg colorspace.
    Reference values from X-Rite ColorChecker Classic converted to ACEScg.
    Layout: 4 rows x 6 columns = 24 patches
    Each patch is a 1x1 quad with MaterialX standard_surface material.
    ACEScg values (scene-referred, AP1 primaries, linear encoding).
    Uses MaterialXConfigAPI for DCC interoperability.
