Multiline pastes into the web terminal (especially into pi) were split into one prompt per line because bracketed-paste markers were not reaching the foreground app intact. - Put the host PTY into raw mode (tty.setraw) after openpty() so it acts as a pass-through pipe. The default canonical line discipline was line-buffering input, splitting multiline pastes at newlines, and mangling bracketed-paste markers before docker exec / pi could see them. The in-container PTY (docker exec -t) provides real discipline. - Route the mobile Paste button through xterm.js (term.paste) instead of sending raw clipboard text to the WebSocket, so content is wrapped in bracketed-paste markers when the app has enabled BPM. - Treat a text frame as a control message only when it is a JSON object with a known type (resize/ack/reset); otherwise forward as raw input so JSON-shaped pastes are no longer silently dropped.
