Quit it. Reboot it. You never lose work.

Reboot, and every pane comes back in its directory over its old scrollback, with omp mid-conversation. tern remote serve does the same for a server over QUIC.

03Graphics

Diagrams, math, web pages. Faster than a TUI draws text.

Mermaid, LaTeX, diffs, live pages. Modern graphics, without the web stack's baggage: programs describe their UI over the Tern Surface Protocol, and Tern draws it natively.
