== Background
Coming from T330694, there has been 10 deprecated legacy tokens in WikimediaUI Base identified.
Colors and line-height are at maximum quick exchanges with designers/volunteers on the affected products.
Exchanging the breakpoint variables on the other hand has a minimal potential for a change in user-interface presentation. For one, the tablet breakpoint is decreased by 80px, pushing lesser devices into a mobile phone only experience. Second, desktop and desktop-wide kicks in later, by 120px and 480px each.
Specifically latter change will need a closer look when testing the patches.
**Note that these changes are an important predecessor to work on a unified Grid in our interface. Without having one reliable breakpoint source, we can't ensure consistent design expectations!** See {T337282} for the Codex part of it.

== Proposal
Find a design-approved way to remove the deprecated tokens that don't have a 1:1 replacement value-wise.
