On Special:NewLexeme, we would like to use Codex design tokens as CSS variables (see T375370 for details). However, currently only a subset of design tokens is made available as CSS variables (see shouldExposeCustomProperty), and even then only a subset of skins seem to include these CSS variables (they’re included in Vector 2022 but not in legacy Vector).

Is it possible to add additional CSS variables for more design tokens? (If needed, we could supply a list of which specific design tokens we use once we’re mostly done with T327684.)
