//! Run with: cargo run --example auto_connect_bambu
//!
//! For each Bambu printer in printers.toml, makes sure it has a working
//! certificate, auto-pinning one via trust-on-first-connect if the
//! bundled CA doesn't verify - the exact same `ensure_trusted` step
//! `BambuPrinter::connect()` runs before opening MQTT, isolated here so
//! you can check/establish trust without needing a full MQTT handshake to
//! succeed too. Safe to run repeatedly - a printer that's already pinned
//! (certs/pinned/<serial number>.pem) just gets re-verified against its
//! pin, no network trust decision is made again.
