Thanks @veena14cs. Just a few comments left. Some of them might be correct as-is per your earlier comments, but I just wanted to double check.

LGTM, thanks.

[BenHenning]

Thanks @veena14cs! I have nothing else to add. I think this is a really nice change toward centrally managing RTL properties, and sets us up for more cleanly organizing centralized styles & enforcing their presence in future work.
