MeowOS-For-R3P2/patch_v2/sdk/test_meow_md3.c

/* test_meow_md3.c — 宿主验证 MD3（Material You）对齐修复（agent-434 P0/P1/P3）：
 *   P0 listview 容器模式（默认 renderer：行=surfaceContainer 圆角卡 + 行间空隙 + 去分隔线）；
 *   P1 按钮胶囊化（圆角=h/2）；
 *   P3 Switch off-track/off-thumb、NavigationBar active pill 64×32、Checkbox/Radio 视觉尺寸。
 * 断言全部「画完读 back_buf 像素」（region_has/px_near），不依赖 /dev/fb0/字库（meow_font 打桩）。
 *
 * 编译（宿主 gcc，链真实 gfx/sys/theme/vol/log/widget/input/activity/dialog/ime + 打桩 font/global）：
