/**
 * RMT5 Device Hardware Abstraction Macros
 *
 * Purpose:
 * - Zero-overhead platform-abstracted RMT register access
 * - Macros guarantee inline expansion with no function call overhead
 * - Direct access to global RMT singleton (ESP-IDF hardware abstraction)
 *
 * Design:
 * - Pure preprocessor macros for guaranteed inlining in ISR context
 * - Platform detection via CONFIG_IDF_TARGET_* macros
 * - Uppercase naming convention for macro visibility
