Changed label to native-extension (per #169). pyperclip 1.11.0 is a pure-Python source tree, but its documented public API (pyperclip.copy() / pyperclip.paste()) auto-detects and shells out to external binaries on every supported platform:

• macOS: pbcopy / pbpaste (src/pyperclip/__init__.py:100, :105)
• Linux X11: xclip / xsel (:167, :175, :195, :203)
• Wayland: wl-copy / wl-paste (:221, :224, :231)
• KDE: qdbus (:241, :248)
• WSL: clip.exe / powershell.exe (:469, :477)
• Backend probing: subprocess.call(['which', name]) (:80-81)

It also loads the non-stdlib native libraries user32.dll / kernel32.dll via ctypes.windll on Windows (:329-371).

There is no pure-Python fallback — without one of the platform backends, copy()/paste() raise PyperclipException — so it cannot be carried as pure-python even with a caveat.

(native-extension is an imperfect fit semantically — the failure is a runtime-binary / runtime-DLL dependency rather than a compiled C/Rust extension — but it is the closest existing label to "not installable/usable on a pure-Python target".)
