/* test_power_menu_widgets.c — M7.0b 电源菜单控件化宿主验证。
 *
 * 复现 show_power_menu() 所建控件集（pm_widgets_create：meow_card + 6 圆钮，BACK/CANCEL 走
 * meow_iconbtn、POWER/RESTART/UPGRADE/LOCK 走 meow_widget_custom_create 圆形画布），验证：
 *   P1 圆形命中：圆心命中、角部不命中（区别于矩形命中）；
 *   P2 owner==哨兵 + enabled 双闸门（非 active / 禁用不命中）；
 *   P3 选中/按压态像素变化（SDK 状态层，selected/pressed 改侧像素）；
 *   P4 主题四态（MD3/MIUIx × 明暗）下卡片+圆钮渲染非背景像素 + meow_theme_export 九字段映射。
 *
 * 几何常量与 power_menu.c（pm_cy/pm_cx=util.c 同源）/meow_launcher_internal.h 镜像；
 * 控件创建方式与 pm_widgets_create 同（owner=哨兵 0x50，back/cancel 用 MEOW_ICON_*）。
 *
 * 编译（在 patch_v2/meow_launcherd 下）：
