KeyBase font lowercase L and capital I look too similar

I guess this could be considered somewhat pedantic; however, for me, it has lead to some confusion in conversations over KeyBase. The character for a lowercase L `l` and a capital I `I` look incredibly similar — they are the same height and shape, and the only difference is that the L is slightly skinnier, though by an amount still not distinguishable on the majority of displays.

The issue identifies a visual problem in the Keybase font but names no file, test, or entry point. Start by locating the font assets and the UI surfaces that use them, then compare the lowercase l and capital I across supported displays; done means the glyphs are reliably distinguishable.
