+### Slug-Regel wird erzwungen
+
+Ein Slug muss ein sauberes URL-Segment sein: **Kleinbuchstaben, Ziffern und
+einzelne Bindestriche als Trenner, keine Umlaute** (`ueber-uns`, nicht `Über uns`).
+Das ist keine Bitte, sondern eine Feldregel: PocketBase weist einen Slug ab, der
+sie verletzt, und zeigt beim Speichern einen Fehler. Gibst du `Overview` ein,
+kommst du erst weiter, wenn du `overview` daraus machst. Die Website verlässt sich
+darauf — sie repariert einen Slug nicht mehr nachträglich.
+
+Die Regel steckt als **Pattern** am Feld `slug`. So ist sie gesetzt (einmalig,
+pro Collection mit einem Slug — `pages` **und** `posts`):
+
+1. Collection öffnen → *Edit collection* (oben rechts) → Feld `slug`.
+2. Am Feld auf das **Zahnrad** (Feldoptionen) → **Pattern**.
+3. Als Pattern eintragen: `^[a-z0-9]+(-[a-z0-9]+)*$`
+4. **Save** (Feld) und **Save** (Collection).
+
+Zum Prüfen: `board`, `ueber-uns`, `faq-lunch` werden angenommen; `Overview`,
+`über-uns`, `my page`, `-x` und `a--b` werden abgewiesen.
