1//! Child-process conventions shared by every vendor that shells out.
2//!
3//! `ai-usagebar-tray` is a `windows_subsystem = "windows"` process: a console
4//! child spawned from it gets a brand-new console window, which takes the
5//! foreground and blurs the popover (which then hides). Every helper that runs
6//! a CLI for its data must therefore pass [`CREATE_NO_WINDOW`] on Windows.

8/// `CREATE_NO_WINDOW` from `PROCESS_CREATION_FLAGS`. Spelled out rather than
9/// imported so the vendor modules stay free of the `windows-sys` feature list.
