// 方向校准卡（Windows Pavo 直打校准用）：642×1014 纵向，四角 ▲■●◆ + 中央大写 F + 左右箭头。
|
||
// 打一张即可从 8 种变换（4 旋转 × 2 镜像）中唯一定出打印机的实际映射。
|
||
//
|
||
// 用法（在项目根目录）：
|
||
// dart run tool/make_test_card.dart # 只生成 build/calibration_card.png
|
||
// dart run tool/make_test_card.dart --print # 生成并直接 POST 到本机助手打印一张
|
||
//
|
||
// 放卡方式与正式打印一致：打印面朝上、文字对着自己。
