"""
Level 8: Delimiter Attacks - Challenge Definitions
----------------------------------------------------
Concept: Break out of the prompt structure itself.
Difficulty: Advanced (targets use structured prompt templates)

The paradigm shift: instead of tricking the AI with words,
you exploit how the prompt is STRUCTURED. XML tags, JSON fields,
markdown formatting, comment syntax, and template variables are
all attack surfaces. If the bot uses structure, you can break it.
