Most importantly: Are the masks and social distancing mandated by law in Austin?

I'm sure that the US of A is very divisive on this because some states you do not see masked people and others do even if not mandated by law.

(For reference, in Hong Kong, the masks are actually mandated by law but all you have to do is to pull the mask down (although it still hurts having that thing around your chin) and so far I had entered trains like that without a fine. Train/mall staff will still scold me but they haven't asked me for fines, and I think they won't even bother if there are no jurisdictional consequences for the unmasked.)
