MeowOS-SDK/sdk/test_meow_ui_anim.c

/* test_meow_ui_anim.c — §12.2 meow_anim 动画基座宿主验证：
 * 缓动数值（tween 中点/终点）、生命周期（start/update/done/cancel）、并行多动画、脏区 flush。
 * 时间推进用真实 usleep（meow_ui_time_ms 是单调钟），对中点用宽容差、终点/取消做精确断言。
 *
 * 编译（宿主 gcc，链真实 gfx/sys/theme/vol/log/widget/draw/activity/ime + 打桩 font/global）：
 *   gcc -o test_meow_ui_anim test_meow_ui_anim.c test_host_stub.c \
