/* test_host_icon.c — 宿主最小 harness：复现主界面卡片（menu_draw_grid_cell）的
|
||
* 「卡底 → 图标 → 名称」绘制序列（与实际菜单同序），断言图标区像素非空。
|
||
*
|
||
* 背景：真机「应用图标完全不渲染（连首字母占位都无）」。本 harness 用真实 SDK（gfx+img）
|
||
* 按实际调用顺序绘制，对「有图（meow_ui_img_cover 不透明 226×226）」与「无图（primary
|
||
* 圆角块占位）」两分支各断言图标区含非背景像素；另转 PPM 目检。
|
||
*
|
||
* 编译（在 patch_v2/meow_launcherd 下）：
|
||
* gcc -o test_host_icon test_host_icon.c ../sdk/test_host_stub.c \
|
||
* ../sdk/meow_ui_gfx.c ../sdk/meow_ui_sys.c ../sdk/meow_ui_theme.c \
|
||
* ../sdk/meow_ui_vol.c ../sdk/meow_ui_log.c ../sdk/meow_ui_widget.c \
