Educational security CTF. This is a learning game about prompt-injection defenses. Every level targets an offline, deterministic mock AI, and the "secret" is a fake token generated for the game. No real accounts, credentials, API keys, or personal data are involved, and nothing here is a tool for use against real systems or people.
