The Platform Abstraction Layer provides (yet) a set of portable types, error codes and logging macros that hide platform-specific details behind a common API. On ESP32 targets, the underlying implementations delegate to ESP-IDF primitives; on other POSIX-compatible platforms, lightweight fallbacks are used instead.

Including this header pulls in the full PAL surface area:

• pal_log: logging macros (PAL_LOGx, PAL_LOG_BUFFER_HEX).
• pal_err: error type, error codes, and checking macros.
