// --- Clipboard integration ---------------------------------------
//
// Three independent paths all route to the system clipboard:
//
// 1. **Selection → Ctrl+C (or Cmd+C on macOS).** Ink's own handler
// in useInputHandlers.ts turns Ctrl+C into a copy when the
// terminal has a selection, then emits an OSC 52 escape. Our
// OSC 52 handler below decodes that escape and writes to the
// browser clipboard — so the flow works just like it does in
// `hermes --tui`.
//
// 2. **Ctrl/Cmd+Shift+C.** Belt-and-suspenders shortcut that
// operates directly on xterm's selection, useful if the TUI
// ever stops listening (e.g. overlays / pickers) or if the user
// has selected with the mouse outside of Ink's selection model.
//
// 3. **Ctrl/Cmd+Shift+V.** Reads the system clipboard and feeds
// it to the terminal as keyboard input. xterm's paste() wraps
// it with bracketed-paste if the host has that mode enabled.
//
// OSC 52 reads (terminal asking to read the clipboard) are not
// supported — that would let any content the TUI renders exfiltrate
// the user's clipboard.

// smaller than one cell's width, fit() computes the same integer
// (cols, rows) as before and doesn't emit onResize — so the PTY
// never learns the final size. Users see truncated long lines until
// they resize the browser window.
