Crashed or failed to run in a reasonable time
Add a host over ssh and its shells, agents, and browsers join your local ones in the same window. Everything stays quick, even on a bad link.
Split a real Chromium next to the shell you are working in. Open one from a script or choose Browser in Settings → Multiplexer for your split shortcut. It resizes with the same drag and reattaches on the same URL.
browser →First launch finds your tmux and Ghostty files and offers to bring them over. The prefix table arrives verbatim, the theme and font as plain values. Neither original is touched.
compat →macOS and Linux. App bundle plus zz on your PATH; brew install --cask demfabris/zz/zz and paru zz-bin work too.
