/**
* X.509 Certificate extracted from Bambu Connect desktop application.
*
* Background: In January 2025, Bambu Lab pushed firmware updates that
* required authentication for local LAN printer control, breaking all
* third-party tools (OctoPrint, Home Assistant, etc.). Community researchers
* extracted the X.509 certificate and private key from the Bambu Connect
* desktop app, enabling third-party tools to authenticate with printers.
*
* These credentials are already publicly available:
* https://hackaday.com/2025/01/19/bambu-connects-authentication-x-509-certificate-and-private-key-extracted/
*
* Can be overridden via BAMBU_APP_PRIVATE_KEY and BAMBU_APP_CERTIFICATE
* environment variables for when Bambu Lab rotates these credentials.
