+ * The kinds of thing that can be booked.
+ *
+ * **This enum is the extension point.** The dashboard builds one tile per case, the board route
+ * accepts one slug per case, and the floor plan is looked up by convention from the case's
+ * value. Adding a third bookable kind is therefore: a case here, a
+ * `templates/board/plan/_<value>.html.twig` with its geometry, and rows in `app:seed`. Nothing
+ * else needs editing — in particular no template lists the kinds by hand.
+ *
+ * The backing values are persisted in `resource.type`, which is why they stay English while the
+ * URLs do not: `slug()` is what appears in a path, so the routes read German like the rest.
