"""Started with DEBUG, the logs still carry no credentials.

httpx and httpcore log every request URL at INFO/DEBUG, and some carry
credentials (bot tokens, webhook URLs, API keys in the query). The SQL echo and
aiosqlite log every statement's parameters, among them every secret saved. The
runtime log-level toggle already kept these quiet; a start with the DEBUG
environment variable did not.
