//! `cargo run --example win_platform_services --features win` (Windows only)
//!
//! Manual smoke test for issue #23's `WinPlatformServices`: clipboard
//! round-trip, native file open/save dialogs, a `Shell_NotifyIconW`
//! balloon notification, and `open_url` — plus issue #744's
//! `TaskDialogIndirect`-backed message dialog.
//!
//! Draws nothing — like `win_demo`, every `WinBackend::draw_*` rasteriser
//! is still a `todo!()` stub (no `draw_status_bar` to report results
//! in-window with), so this exercises `backend.services()` directly from
//! `AppLogic::handle` and reports results to stderr — the console this
//! example is launched from — instead of an in-window status bar. Once a
//! later issue lands the Direct2D status-bar rasteriser, this can be
//! rewritten to share `examples/common/file_dialog_demo.rs`'s in-window
//! status the way `gtk_file_dialog`/`tui_file_dialog` already do.
//!
//! Controls:
//! - `c` — write a fixed string to the clipboard, then read it back and
//! report whether it round-tripped
//! - `o` — native file-open dialog (filtered to `*.rs`)
//! - `s` — native file-save dialog (initial name `untitled.txt`)
//! - `n` — fire a balloon notification (watch the notification area)
//! - `m` — native message dialog (`TaskDialogIndirect`, #744) with
//! Save/Don't Save/Cancel buttons; reports which one was chosen
//! - `u` — `open_url` a fixed address (the default browser should launch)
//! - `t` — query the OS light/dark/accent/high-contrast preference
//! (`system_theme`, #952) and report it; flip Windows' Settings ->
//! Personalization -> Colors "Choose your mode" between runs to see the
//! answer change
//! - `f` — `reveal_in_file_manager` (#956) a freshly-written temp file —
//! an Explorer window should open with it selected
//! - `p` — `open_path` (#956) that same temp file with its default
//! handler
//! - `x` — write a *second* temp file and `move_to_trash` (#956) it —
//! check the Recycle Bin afterward
//! - `b` — `beep` (#956)
//! - `d` — issue #959's `displays`/`cursor_screen_point`: prints every
//! connected monitor (bounds, work area, scale, primary) and the
//! current cursor position to stderr — move the window to a second
//! monitor and press `d` again to see the list/cursor position change
//! - `Esc` / `q` — quit
//!
//! `quadraui::win::run` only exists when compiled for `target_os =
//! "windows"` (see `src/win/mod.rs`/`Cargo.toml`'s `win` feature
//! comment) — this example is Windows-only, same posture as `win_demo`
//! (see that example's module docs).
