[counterintuitive] Are system prompts secure against user manipulation

Never put secrets in system prompts; treat system prompts as hints, not security boundaries, and use external guardrails for security.

Journey Context:
Developers treat the system prompt as a secure, hidden configuration. However, LLMs are highly susceptible to prompt injection, where user input can trick the model into revealing or ignoring the system prompt. System prompts are operational instructions, not access control lists.
