Update for those who were curious:

Roughly one hour after I e-mailed @elithrar who kindly reached out and offered to expediate the issue, the broken DNSSEC records were partly fixed. The domain once again resolved through all major DNSes, and public access was restored. At that point dnsviz.net told me that A, MX, etc. records were "insecure", though name resolution worked fine. A few minutes ago I took another look with dnsviz and it's now telling me that all records are secure. Everything looks normal again.

Thanks a bunch for helping out, @elithrar. I really appreciate that you were proactive.

If the problem had somehow fixed itself or if the support ticket had gotten any attention or feedback at all within a day or two instead of just being "snoozed" by support staff, I wouldn't have made any noise about it. After four days of complete silence a bit of "cry-baby consumer activism" seemed like the only resort.

If CF reconnects to me with an update on why the domain dead-locked and why it took 4 days to untilt everything I'll add that info as well.

I've been OP and this has been an update about my domain woes.
