Preventing Memory Leaks in Embedded C++

In embedded C++, memory leaks = disaster for long-running devices. Prevent them by:

🔹 Prefer stack/static allocation over heap
🔹 Use RAII (unique_ptr, destructors) for ownership
🔹 Pre-allocate, never malloc in ISRs or hot loops
🔹 Keep lifetimes clear & explicit
🔹 Test with sanitizers, leak counters, and static analysis

Leak-free code = reliable systems that run for years.
