+/* 
+ * 📍 TECHNICAL NOTES
+ * 1. The contract uses ^0.8.19 which includes important safety features like:
+ *    - Overflow/underflow checks
+ *    - More strict typing
+ *    - Better error handling
+ *
+ * 2. Storage considerations:
+ *    - The 'data' variable uses a dynamic string which can grow/shrink
+ *    - Each storage operation costs gas based on string length
+ *
+ * 3. Gas optimization notes:
+ *    - Uses 'calldata' for input string to save gas
+ *    - Combines storage and event emission in one operation
+ *    - String storage is relatively expensive, especially for longer strings
+ *
+ * 4. Security considerations:
+ *    - Function is payable but doesn't handle received ETH
+ *    - No access controls on the test function
+ *    - No string length limits enforced
