Design a comprehensive {{course_name}} course in {{course_area}} that progresses from foundational concepts to advanced mastery. Use a {{tone}} tone throughout. Organize into three modules: Beginner (core concepts, no prior knowledge assumed), Intermediate (applied techniques), and Advanced (expert-level synthesis). Each module must include learning objectives, detailed explanations with concrete examples, and practice exercises. Explain concepts in plain language before introducing technical terms. Output as a structured outline with modules, lessons, key takeaways, and one example per lesson. Maximum 1500 words. Paste any relevant background information after these instructions before running.
