/* FreeRTOSConfig.h - STM32F103RC (Cortex-M3, Keil ARMCC) 定制配置
 *
 * 内存预算（RAM 总计 48KB）：
 *   裸机存量 ZI ~36.3KB（U2_CopyBuff 20K + Rx_Buf 8K + OTA块 3K + 杂项）
 *   FreeRTOS 堆 10KB：net任务栈 3KB + app任务栈 2KB + sys任务栈 1KB
 *                    + idle任务 512B + TCB/互斥锁 + 余量
 *   合计 ~46.3KB < 48KB
 *
 * HAL 时基：SysTick 归 FreeRTOS 当 tick，HAL 时基改用 TIM2
 * （见 Src/stm32f1xx_hal_timebase_tim.c），两者都是 1ms。
