+  PROTOTYP — WEGWERFCODE. Nicht in die App übernehmen.
+
+  Drei Varianten des Selector-Bildschirms, umschaltbar über ?variant=A|B|C,
+  dazu die Zustände über ?state=filled|empty|dialog.
+  Frage, die er beantwortet: Gitea-Issue #8 "Selector-UI: Anlegen und Öffnen".
+
+  Doppelklicken zum Öffnen. Bindet die echte CSS des Projekts ein, damit
