Style Analysis Complete:
  Structure: Flow-based with pseudocode
  Language: Procedural, detailed
  Organization: Sequential phases
  Key Patterns: 3-5 phases, function definitions, ASCII diagrams

Recommendations:
  ✓ Use phase-based structure (3-4 phases)
  ✓ Include pseudocode for complex logic
  ✓ Add ASCII flow diagrams
  ✓ Maintain concise documentation style
