🔄 Standardized Documentation Structure

Each function library follows the same documentation pattern:

function-library/
├── README.md                          # Quick reference & overview
├── FUNCTION_LIBRARY_FLOWCHART.md      # Visual execution flows
├── FUNCTION_LIBRARY_FUNCTIONS_REFERENCE.md  # Alphabetical reference
├── FUNCTION_LIBRARY_INTEGRATION.md    # Integration points
├── FUNCTION_LIBRARY_USAGE_EXAMPLES.md # Practical examples
└── [FUNCTION_LIBRARY_ENVIRONMENT_VARIABLES.md]  # (if applicable)

Advantages:

• ✅ Consistent navigation across all libraries
• ✅ Quick reference sections in each README
• ✅ Visual flowcharts for understanding
• ✅ Complete function references
• ✅ Real-world usage examples
• ✅ Integration guides for connecting libraries
