// ===========================================================================
//
// Prompt injection occurs when an attacker manipulates an LLM through crafted
// inputs, causing the LLM to unknowingly execute the attacker's intentions.
// This can include overriding system prompts, injecting new roles, or using
// encoded payloads to bypass detection.
//
// Reference: https://owasp.org/www-project-top-10-for-large-language-model-applications/
