+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The packed attribute tells the compiler not to add any padding between fields in memory. This makes the struct:
+
+ - Compact
+ - Predictable for serialization over protocols like UART or ESP-NOW
+ - Ideal for low-latency transmission in embedded systems
+
+This ensures the receiver interprets the exact byte layout you expect, minimizing bandwidth and maximizing compatibility across platforms.
