+# 🚀 Modul-Starter-Template für philippurbschat.de
+
+Dieses Verzeichnis dient als Kopiervorlage für neue Mini-Projekte und Experimente.
+
+## In 30 Sekunden startklar:
+
+1. **Ordner duplizieren:**
+   Kopiere diesen `_template`-Ordner und gib ihm den Namen deines neuen Projekts (z.B. `synth`, `todo`, `scanner`).
+   ```bash
+   cp -r _template mein-projekt
+   ```
+
+2. **Metadaten in `module.json` anpassen:**
+   Öffne `mein-projekt/module.json` und passe Name, Badge und Beschreibung an:
+   ```json
+   {
+     "name": "Mein Tolles Tool",
+     "badge": "AI Lab",
+     "description": "Was das Tool macht",
+     "adminOnly": false,
+     "order": 10
+   }
+   ```
+
+3. **Fertig!**
+   * Das Modul erscheint sofort automatisch in der Benutzerverwaltung unter `philippurbschat.de/admin/users`.
+   * Es erbt automatisch das Dark-Theme, Tailwind v4 und Typografie von `philippurbschat.de`.
+   * Es hat sofortigen Zugriff auf `GEMINI_API_KEY` aus der zentralen Konfiguration.
+
+---
+
+## Features & Architektur
+
+* **Graceful Auth (`bootstrap.php`):**
+  * Auf `philippurbschat.de`: Vollständig geschützt durch Session & Rechteverwaltung.
+  * Standalone-Betrieb: Wenn du den Ordner als eigene Website auslagerst, läuft er ohne Änderungen direkt weiter.
+* **Hierarchische API-Keys:**
+  * Rufe in PHP `module_env('GEMINI_API_KEY')` auf.
+  * Wenn im Modulordner eine eigene `.env` liegt, hat diese Vorrang. Andernfalls greift automatisch der globale Key aus `/home/.env`.
+* **Sicherer API-Proxy (`api.php`):**
+  * Verhindert das Offenlegen deiner API-Schlüssel im Frontend.
