Re: [csswg-drafts] [css-fonts] Proposal to extend CSS font-optical-sizing (#4430)

1. `[font-optical-sizing](https://www.w3.org/TR/css-fonts-4/#font-optical-sizing-def)` should be reviewed and checked for consistency with the updated axis description. CSS isn’t my area, but I feel it may be helpful to pick up on the stuff in the axis description re. units, so this is explicit in the CSS text also. Perhaps also an example or two of how to interpret opsz values relative to pixel density?

2. Consider adding explicit opsz value override—e.g. `font-optical-size=14`—that authors could use for stylistic effect or because e.g. they are creating content for signage displays or other situations in which distance from display is assumed to be greater than typical.

3. Consider adding relative opsz value override that authors could use to tune font optical size, e.g. `font-optical-sizing=-2` which would display the opsz value 2 below the auto size value.
