• Reduced Documentation Bloat: Decreased README size by 83 net lines, making the file more concise and easier to maintain
• Minor Polish: Added an exclamation mark to the Contributors section ("Thanks to everyone who has contributed to this repository!") for improved tone and engagement

• Performance: No performance impact. Documentation changes do not affect runtime behavior or build performance.
