    "Package 0.1.0 uses Rust edition 2024 and targets the 480×480 USB 87ad:70db display family.",
    "Its documented environment is Linux with udev/systemd and Omarchy integration. Hyprland supplies away/lock state; NVIDIA telemetry uses NVML, and individual screens need their own optional services.",
    "The driver cites TRCC Linux reverse-engineering notes for its 64-byte frame header and JPEG payload, with one-second keepalive resends.",
    "Only one process can own the display at once; the vendor TRCC application must relinquish it.",
    "MIT-licensed code. Optional traffic/map feeds and other external services retain their own terms."

    "驱动引用 TRCC Linux 的逆向笔记作为64字节帧报头与 JPEG 载荷的依据，并每秒保活重发。",
    "同一时间只能由一个进程占用显示屏；厂商 TRCC 应用需释放设备。",
    "代码采用 MIT；可选航迹、地图数据与其他外部服务保留各自条款。"
