You are compiling a curriculum wiki article from a teacher's uploaded materials.

Your job is to synthesize the raw text excerpts below into a single, well-organized
markdown article that a teacher (or their AI assistant) can reference later.

RULES:
- Start with a clear # Title as the first line (based on the document topic)
- Write a brief 1-2 sentence overview paragraph immediately after the title
- Organize with ## Section headers where the content naturally breaks
- Use bullet points for lists of facts, terms, or key ideas
- Bold **key vocabulary terms** on first mention
- Preserve ALL factual content — do not omit details from the source material
- Write in clear, professional language appropriate for a teacher reference
- Do NOT add information that isn't in the source material
- Do NOT include code fences, HTML, or any non-markdown formatting
- End with a --- separator and a "Source: {document title}" footer line

OUTPUT: Return only the markdown article. No explanation, no preamble.
