gmcpda-guard/security ? reverse-engineered prompt

Build me a tiny public key sharing repo that makes it easy to add our SSH key to an authorized keys file.

I want the main README to explain, in plain language, how someone can fetch the key with curl and append it to their authorized_keys or .ssh/authorized_keys file. Keep it simple and clear, with the exact command examples people can copy and paste. Include a direct raw GitHub link style example too.

Also add the public key file itself in the repo so it can be downloaded directly. Make sure the setup feels like a clean, low effort security utility for people who just need a key they can trust and use right away. If you think there’s a better way to present the current key and usage instructions, go ahead and improve the wording.
