 * @brief   CBR1 红绿 LED 事件表：跟继电器 / 配对 / OTA（规格书第 6 章）
 * @author  cyWu <1917507415@qq.com>
 * @date    2026.09.04
 * @version V1.0.0，P0 Bring-up（由门夹双通道事件表裁剪：删电池/充电/模式事件）
 *
 * @note    加热垫红绿互斥（一次只一种图案），高事件（配对/结果/OTA）添加前
 *          app_led 层先全清事件+灭灯；事件结束自删后 app_led_run 按继电器
 *          实际态自动重新挂 HEAT 事件。
