v154 · font-width
The CSS side
The same rename, in the stylesheet. font-width as a property and as an @font-face descriptor, checked against font-stretch — with the computed values read off real elements, because CSS.supports() tells you a value parses and not what it became.

The keyword ladder
The keywords are shorthand for percentages, and knowing which is which matters when you are matching a variable font's wdth axis to a design token.
A percentage is the general form; the keywords exist because they were there first. Both names accept both syntaxes, so a rename does not force a rewrite of the values.
