## Clipboard providers
macOS uses fixed JXA/AppKit `NSPasteboardTypeString` access through `osascript`, preserving literal RTF/EPS text rather than treating it as rich clipboard data. Linux supports Wayland with `wl-paste`/`wl-copy`, or X11 with `xclip`, on PATH with the corresponding display environment. Other platforms report unsupported access. Commands have a two-second deadline and bounded output; failures terminate/reap their process group.
macOS publishes `public.utf8-plain-text` through the native Pasteboard Manager, checking allocation and OS-status failures before reporting success. Publication is synchronous and avoids per-copy interpreter/process startup; native calls do not have a subprocess deadline. Reads retain fixed JXA/AppKit `NSPasteboardTypeString` access through `osascript`. Both paths preserve literal RTF/EPS text rather than treating it as rich clipboard data. Linux supports Wayland with `wl-paste`/`wl-copy`, or X11 with `xclip`, on PATH with the corresponding display environment. Other platforms report unsupported access. Subprocess-backed access has a two-second deadline and bounded output; failures terminate/reap the process group.
