Constrained Chunking Strategy Design

Design a document chunking strategy within strict constraints.

CONSTRAINTS:
- Maximum chunk size: {{max_tokens}} tokens
- Minimum chunk size: {{min_tokens}} tokens
- Overlap requirement: {{overlap_percentage}}%
- Must preserve: {{preserve_elements}}

Document Characteristics:
{{document_types}}

OUTPUT FORMAT:
```yaml
chunking_strategy:
  base_method: [semantic|fixed|sentence|paragraph]
  chunk_size: <tokens>
  overlap: <tokens>
  
boundary_rules:
  - type: <element>
    action: [preserve|split|merge]
    
special_handling:
  - document_type: <type>
    modifications: [<adjustments>]
    
validation:
  constraint_compliance: true
  expected_chunks_per_doc: <range>
```
