• docket graph --web serves a live, localhost-only browser view of the relation graph, with --port N to pick the port.
• The w key in the terminal graph viewer opens the web view for the current filter.
• docket export --group none|kind|scope draws boxes around records, and --focus ID --hops N draws only a record and the records within N relation steps of it.
• The docket graph --web page has a Layout popover for engine, direction and grouping, and a "Focus here" control in the record drawer. Layout state is kept in the URL query string.

Changed
