//! Embeds a Windows .exe icon when `MKGRAPHIC_APP_ICON` is set.
//!
//! No-op on every other platform, and a no-op on Windows too unless the env
//! var is set - packaging tooling (`cargo xtask bundle-windows`) sets it
//! before invoking `cargo build`; a plain `cargo build`/`cargo run` is
//! unaffected.
