// Hard cap on displayed prompt text. Piping large files via stdin

// <Text> node the fullscreen Ink renderer must wrap/output on every frame,
// causing 500ms+ keystroke latency. React.memo skips the React render but
// the Ink output pass still iterates the full mounted text. Non-fullscreen
// avoids this via <Static> (print-and-forget to terminal scrollback).
// Head+tail because `{ cat file; echo prompt; } | claude` puts the user's
// actual question at the end.
