//! Windows only: embed version info (VERSIONINFO) into `pdfcraft-cli.exe`, so Explorer's
//! Details tab, `(Get-Item pdfcraft-cli.exe).VersionInfo` and inventory tools can read the version
//! and publisher, as they can for `pdfcraft.exe` (`apps/pdfcraft/build.rs`).
//!
//! On every other target this does nothing. A missing resource compiler is a warning, so a
//! cross-compile from macOS or Linux still links, unless `PDFCRAFT_REQUIRE_WINRES=1` turns it
//! into an error (for release builds).

/// The in-box DLLs only printing uses (Windows.Data.Pdf draws the job, prntvpt reads the
/// driver's print capabilities). Trimmed Windows installations (NTLite) can lack them, and a
/// load-time import of a missing DLL stops the program before `main` (#2630). Delay-loaded, they
/// load on the first print; `pdfcraft_print::spool` checks they exist before calling in.
/// Same list in `apps/pdfcraft{,-cli}/build.rs`, `crates/print/build.rs` and `crates/print/src/spool.rs`.
