"""
You are a document chunking specialist. Your task is to chunk a new document to analyze where this document content aligns clearly with the reference chunks of a reference document and match the EXACT STRUCTURE and of a reference document, wherever the content strongly aligns.

Whereever it doesnt align, just chunk without trying to match the reference chunks structure, just chunk that content to roughly meet {target_size} characters, ensuring to break at smart points.

STRICT REQUIREMENTS:
1. ONLY split the text into chunks. NEVER modify, rephrase, paraphrase, summarize, or omit any content. Each chunk must contain the original text exactly as it appears in the input.
2. Break at sentence boundaries, NEVER mid-sentence
3. Break at paragraph boundaries when possible
4. MOST IMPORTANT: ALL content of the new document must be included in the chunks, without any information being missing!


STRUCTURAL TEMPLATE MATCHING:
1. The reference chunks serve as your RIGID TEMPLATE - if content strongly aligns with the reference chunks somewhere, match their structure exactly
2. Create the SAME NUMBER of chunks as the reference document
3. Each new chunk should correspond to the same type of content/section as the reference chunks
4. Maintain the same heading/section boundaries as shown in the reference
5. Match the semantic boundaries and conceptual groupings from the reference document exactly
6. Creating more or less chunks than the reference is allowed if the document containts more or less content in total

CRITICAL: NEVER create chunks that contain ONLY section headers (like "Introduction", "Conclusion", "Summary", etc.) without meaningful content. 
Always include the header WITH the content that follows it in the same chunk. If a reference chunk shows a header alone, merge it with the following content instead.

CRITICAL, MUST FOLLOW, overrides any other rule: 
1. NONE OF THE INFORMATION OF THE NEW DOCUMENT CAN BE MISSING.
2. **ABSOLUTE SIZE CAP:** No chunk may exceed {max_size} characters.  

CRITICAL FOR TEMPLATE ALIGNMENT:
- Your PRIMARY GOAL is to replicate the structural pattern of the reference chunks (of course only for text that strongly aligns with the reference chunks)
- The reference document controls the chunk boundaries, wherever the content strongly aligns
- Look for headings, sections, and content organization patterns in the reference
- Create chunks that correspond to the exact same conceptual areas as the reference chunks
- Focus on structural consistency with the reference template rather than optimal chunk sizes
- HOWEVER: Whatever info is not at all similar to the reference chunks, you just chunk with the maximum size in mind!

Format response similar as the doc 1 chunks.
