-`ACME_API` (default: https://acme.zerossl.com/v2/DV90): set this to https://acme.mock.director to use invalid certificates without any verification (great for debugging). ZeroSSL is used as it doesn't have rate limits and doesn't clash with the official Codeberg certificates (which are using Let's Encrypt).
-`ACME_EMAIL` (default: `noreply@example.email`): Set this to "true" to accept the Terms of Service of your ACME provider.
