* ESC Backend Abstraction Layer
|

|
|
* Provides a pluggable interface for different ESC implementations:
|
|
* - Hoverboard (EFeru FOC firmware, UART @ 115200)
|
|
* - VESC (via UART @ 921600, with balance mode) — future
|
|
*
|
|
* Allows motor_driver.c to remain ESC-agnostic. Backend selection

|
* via ESC_BACKEND compile-time define in config.h.

* Issue #388: ESC abstraction layer
