1//! Clipboard helpers for copying plain text via `wl-copy` or `xclip`.
2
3/// What: Copy plain text to the system clipboard without extra suffixes.
4///
5/// Inputs:
6/// - `text`: Exact bytes to place on the clipboard.
7///
8/// Output:
9/// - `Ok(())` when `wl-copy` or `xclip` accepted stdin.
10///
11/// # Errors
12/// - Returns `Err` with install guidance when neither clipboard tool could be spawned.
13///
14/// Details:
15/// - Prefers `wl-copy` when `WAYLAND_DISPLAY` is set, otherwise tries `xclip`.
16/// - Does not invoke a shell; uses `Command` argument lists only.
