# build_ncm_host_mem.sh — 宿主编译 ncm 的真实页面/逻辑（离屏 480x720）+ 内存测量 harness。
#
# 与 build_ncm_host.sh 的差异：
#   * 复用既有 out/host/sdk_*.o（SDL 层既有对象，避免 SDK meow_ui_gfx.c 当前工作区
#     的注释语法缺陷导致全量 SDK 重编失败），仅重编 meow_ui_img.c（新增 meow_img_downscale）。
#   * 用途：验证封面降采样（内存瘦身）在宿主按预期工作；供 mem_sim 报告各场景 RSS。
# 运行：MEM_SIM=1 ./ncm_host（内置内存自测）或 NCM_PAGE=home MEOW_UI_DUMP=/tmp/home.ppm ./ncm_host
