/* test_subpage_widgets.c — M7.1a 子页渲染层迁移（SDK 控件化）宿主验证。
 *
 * 复现 subpage.c 所建控件集（topappbar + 顶开关 meow_switch + listview 虚拟化 vsource +
 * meow_scroll 包裹 fling），验证：
 *   P1 listview 虚拟化渲染：section 段头 + 普通/开关/动作行（right=SWITCH/ARROW）非背景像素；
 *   P2 listview 命中：行号（含滚动换算 + 禁用行不响应）+ right 操作区命中（hit_op）；
 *   P3 topappbar 命中：返回箭头区 → MEOW_TOPBAR_BACK；
 *   P4 meow_scroll 包裹 listview：跟手 track + 松手 fling（meow_anim_tick 驱动）+ snap 到行边界；
 *   P5 SDK 输入态（meow_input_touch_set）→ listview 按压态像素变化；
 *   P6 主题四态（MD3/MIUIx × 明暗）下 topappbar + listview 渲染非背景。
 *
 * 几何常量与 subpage.c / meow_launcher_internal.h 镜像；控件创建方式与 sp_widgets_create 同
 * （owner=哨兵 0x52，listview 用 set_vsource + set_item_renderer(2,0,1) + set_item_h 56）。
 *
 * 编译（在 patch_v2/meow_launcherd 下）：
 *   gcc -Wall -Wextra -o test_subpage_widgets test_subpage_widgets.c \
