+// Package clipboard provides unified clipboard read/write across Linux, Windows, and macOS.
+//
+// On Linux, it auto-detects X11 (xclip) vs Wayland (wl-clipboard) by checking
+// $XDG_SESSION_TYPE and verifying the required binaries at initialization time.
+// On Windows, it uses the Win32 clipboard API via syscall (no CGo).
+// On macOS, it shells out to pbpaste / pbcopy.
+//
+// Each platform file defines its own New() constructor using //go:build tags.
