Research direction

Start by reproducing the font-weight behavior on macOS 11.x and compare it with the accepted behavior on macOS 10.15.x. Investigate the CoreGraphics handling of wght axis values above 900 and determine what mapping, if any, is needed; done means those values are respected on macOS 11.x.
