// Example mod: render a custom entry into the feed with your own styling.
//
// Two pieces:
//   cmd.addRenderer(type, data => lines)  → registers how a custom entry type prints
//   cmd.showEntry(type, data)             → pushes an entry of that type into the live feed
//
// Rendering is line-based: the renderer returns styled terminal lines (use raw ansi escape
// codes, picocolors, or @commandcode/tui helpers). Unrendered types pretty-print as JSON.
// The TUI wires the feed sink; headless runs drop entries. A throwing renderer degrades to
// a warning notice, never a broken screen.
//
// Pair showEntry with cmd.session.appendCustomEntry when the data should also persist to
// the transcript.
