/* test_meow_ui_theme.c — 宿主验证 §8.1 顶级主题：MD3 × MIUIx 各 light/dark 四套配色 & 控件形态。
 *
 * 用法：build 后跑 4 次（每次一个 style×mode 组合，dump 一张 PPM）：
 *   for s in 0 1; do for m in 0 1; do
 *     MEOW_UI_DUMP=/tmp/meow_t_${s}_${m}.ppm ./test_meow_ui_theme $s $m
 *   done; done
 *   s: 0=MEOW_STYLE_MD3 1=MEOW_STYLE_MIUIX; m: 0=light 1=dark
 *
 * 编译（宿主 gcc，链真实 gfx/sys/theme/vol/log/widget/input/activity/dialog/ime + 打桩 font/global）：
 *   gcc -o test_meow_ui_theme test_meow_ui_theme.c test_host_stub.c \
 *       meow_ui_gfx.c meow_ui_sys.c meow_ui_theme.c meow_ui_vol.c meow_ui_log.c \
 *       meow_ui_widget.c meow_ui_input.c meow_ui_activity.c meow_ui_dialog.c meow_ui_ime.c meow_ui_str.c \
 *       meow_ui_draw.c meow_ui_view.c meow_ui_img.c meow_notify_ipc.c stb_image.c \
 *       -I. -I../meow_launcherd -DMEOW_UI_HOST_TEST -pthread -lm
 *
 * 验证要点：四套主题 primary/radius 各不相同（MD3 蓝 / MIUIx 橙 + 更大圆角），
 *      同 style 下 light/dark 的 surface 成对切换；图形用 MEOW_UI_DUMP 导出 PPM 目检。
