+# External Dependencies for names-generator.js
+
+The refactored `names-generator.js` module requires the following external dependencies to be imported:
+
+## Utility Functions
+- `ERROR` - Error logging flag/function
+- `WARN` - Warning logging flag/function  
+- `P` - Probability function (returns true/false based on probability)
+- `ra` - Random array element selector function
+- `last` - Function to get last character/element of a string/array
+- `vowel` - Function to check if a character is a vowel
+- `capitalize` - Function to capitalize a string
+- `rand` - Random number generator function
+
+These utilities should be imported from a common utilities module (e.g., `../utils/index.js`) and passed as a `utils` object parameter to the exported functions.
+
+## Data Dependencies
+- `nameBases` - Array of name base configurations (passed as parameter)
+- `cultures` - Culture data object with base references (passed as parameter from pack data)
+
+## Notes
+- All global state access has been removed and replaced with parameter injection
+- The module is now pure and environment-agnostic
+- No browser or DOM dependencies remain
