- 新增 ota_channel_t(WiFi/BLE) + m_otaEpoch 会话代次， abortCurrentIfEpoch 防止同类型重启后旧 handler 误清新会话 - 同通道再次发起 OTA 时自动中止旧会话并重开 - 统一 prepareGd32Storage(validate+begin+erase+meta)， 消除 BLE/WiFi 两路径隐式差异 - OtaRelay 拆分子步骤(doRelayPackets/doFinishAndVerify)， 状态成员私有化消除数据竞争 - Gd32FlashStore NVS 读写加 mutex，metaUpdate 原子化 - BLE OTA 新增 0xFB 中止命令（保持连接）+ 0x20 ABORTED 处理 - HTTP handler 改 per-request buffer 支持并发 - 修复 CRITICAL 状态 RSSI 恢复无法降级的缺陷 - main.cpp 关键任务失败触发看门狗重启 - style.css 增强动画 + prefers-reduced-motion 兼容
