memoize class-names

[elmarsto]

I use @sindresorhus/class-names liberally throughout my codebase, because it makes tailwind config strings managable. However it also introduces overhead in every render.

Mitigation:

• replace direct calls to this library with calls to a wrapper function, say, @/sbstr8/lib/class-names, that provides memoization (via ramda?
• does useMemo work in server components? A quick google did not find definitive answer -- someone claims that no hooks work, but this is obviously false (usehooks.com etc.). If useMemo() works in server components, this could be a decent implementation path

thinking more about this:

• two separate hooks with the same name could be used, like we do for useOverride().
• client-side hook backed by useMemo()
• server-side hook backed by ramda
