/*
* kt_led7.c — 硬件扫描与段码
*
* 与 kt_led7.h 中 L7～L14 的对应关系：
* L7 → 本文件 kt_led7_scan() 六相状态机（case 0～5）
* L8 → LED_NUMBER / LED_LARGE_LETTER / LED_SMALL_LETTER
* L9～L12 → 由 kt_led7_show_* 填充缓冲后体现（当前为 stub，需与 kt_fan_ac 档位同步）
* L13 → show_time / urgent / 闪烁（待与 disp_buf、策略层补全）
* L14 → USB/电量/灯光等由上层调用 show 接口让路或关显
*
* 说明：逻辑段与 PCB 段的映射见 case 内注释（如 L38-L47 段映射）。
