Could the glyphs/icons be black/grey/inverted too?

It's the only thing missing from making Latte (in my opinion) the prime "Light Theme" for Steam Decks.

Actually now that I think of it, that would be a great idea for an additional separate Theme to the line-up:

Ipoh

Basically, fully white backgrounds with fully black fonts, icons and glyphs system-wide.
