"""
图标/图文点选求解器 回归测试 (AGENTS.md §5.9)

固化的性质:
  1. 提示条(目标原图) -> 背景图 的**形状模板匹配**在真机样本上给出正确、有序的点击点;
  2. 能处理**旋转**目标 (样本里"图表"图标被倾斜 ~-30°);
  3. 能排除干扰图标 (样本里的笑脸/银行).

样本: tcaptcha/tests/fixtures/1ms_icon_click_1_{prompt,bg}.jpg
      取自 1ms.run (aid=195672344) 真机页面上弹出的验证码 (2026-10-11),
      题面 = "0" + 图表图标 + "7", 期望点击顺序与坐标见 EXPECTED。

运行:
    .venv/bin/python -m tcaptcha.tests.test_icon_click_solver
