/* render_sb_statusbar.c — 宿主可视化渲染：把「同一个状态栏」画进 back_buf 并 dump PPM 目检。

* 仅用于宿主验证（无 /dev/fb0 → 480x720 离屏；字体缺失时图标仍画，数值可能缺字）。

* 编译（宿主 gcc）：

* gcc -o render_sb_statusbar render_sb_statusbar.c meow_ui_gfx.c meow_ui_sys.c meow_ui_theme.c \

* meow_ui_vol.c meow_ui_log.c /tmp/meow_font_host.o -I. -I../meow_launcherd -lz
