Background
A small token category, best in typography meta category situated: We also need to define tab-size. It's used in a few places in MediaWiki, and also in VitePress default styles.
This has to be a theme decision that we have to be able to cover.
Context is theme-ability of typographic style in <code> or <pre> elements, in an example like this:
https://www.mediawiki.org/wiki/Manual:Coding_conventions/CSS#Specificity
As folks have strong opinion over text styles, this might be asked to change when using Codex in context outside MediaWiki.
Proposal
theme options:
tab-size-100: 4
decisions
tab-size-base: tab-size-100
Goal
Define tab-size option and decision tokens.
With default value 4 in WikimediaUI theme.
