 * Plugins (#113, #114, #119). The demo plugin in `plugins/` is copied to `data/plugins/` by the
 * build and the seeder; the fixture project switches it on, and the editor loads it before the
 * project itself. What only a running editor can show: that the module really loads and activates,
 * that its tab joins the row, that its node board draws one node per asset and follows the asset
 * list – created through the + menu, renamed, and taken away again by undo – and that the switch in
 * the Plugins tab stops and starts it while the editor runs, as an undo step of the project.
