Styles section, new example: Contextual boldness

[davelab6]

In the course of explaining to a colleague why OS/2 WeightClass values are not very useful, I mentioned this example, which I then realised I don't have an easy citation/reference to.

Within high end typography, there's bold for headlines and then a different bold for paragraph-emphasis, which is not as bold; the amount of boldness in OPQ terms is different for each case. (Perhaps there are more cases.)

With a proper weight scale like parametric axes, "the B button" (or Cmd-B hotkey) can apply a contextually-appropriate and adapted amount of weight, based on the content markup, point size, etc.

But with the OS/2 WeightClass values which are arbitrary and can't be used for inter-family relations/calcuations, we cant build that feature as easily, or, at a deeper and more sublte level, people's minds are mislead to complete confusion as to what weight even is, so that such a feature can't be thought of, and doesn't get built at all.

If you agree, I'd love to see this added, explained and illustrated, in the Styles section.

Don’t we already make the comd-B yield a proper bold, regardless of size, via our pyramidal opsz axis?

From there, in inter-family use, yes only parametric axes can help. And that goes for all other registered axes, as w/out parametric info, “the people's minds are mislead to complete confusion as to what weight”, width, or size are. With parametric values, (w/out even having axes, just the values), we can know all.
