🟡 Changes recommended

The SSLContext precedence test does not establish its claimed behavior, and the example incorrectly promises certificate-option overrides.

Looks good. But...

An update to examples/README.md would be helpful.

The basic mTLS example has a minor style problem.

@karel-rehor
Example added to README.md.
The gittree looks terrible, but I will fix it before I merge.

I was looking for a one-line mention of examples/config_tls_mtls.py in examples/README.md. But the mention in ./README.md is also useful.

Tests pass locally with 3.12

Looks good to me. 🚴 🏁
