+//! Reproducible harness for benchmarking clipboard attachment reads
+//! (the paste hot path).
+//!
+//! Runs one `get_attachments()` — the same unified probe the pager's paste
+//! pipeline executes — and prints the outcome plus wall time. Benchmark the
+//! native in-process read against the `osascript` fallback with hyperfine:
+//!
+//! ```text
+//! # put an image on the pasteboard first, e.g.:
+//! #   osascript -e 'set the clipboard to (read (POSIX file "shot.png") as «class PNGf»)'
+//! cargo build --release -p xai-grok-shared --example clipboard_probe
+//! hyperfine --warmup 2 \
+//!   -n native './target/release/examples/clipboard_probe' \
+//!   -n osascript 'GROK_CLIPBOARD_NO_NATIVE_READ=1 ./target/release/examples/clipboard_probe'
+//! ```
+//!
+//! Exits non-zero when the read errors so hyperfine aborts loudly instead of
+//! averaging failures.
