iOS-Parität zum Web: Item-Modell + API, Einzelstueck-Liste in der Produkt- Detailansicht (anlegen, je-Stueck Lagerort/Kaufdatum/Garantie/Bezugsquelle/Notiz aendern, entfernen mit Grund, QR je Stueck via CoreImage). Anlegen-Formular hat den Schalter "Einzelstuecke". Der Scanner erkennt Einzelstueck-QR (…/i/<UID>) und oeffnet direkt das Stueck. Seed: "Kaufdatum"/"Garantie bis" nicht mehr als Modell-Felder auf Elektronik - diese Angaben gehoeren je Einzelstueck ans Item, nicht ans Modell.
