chore: Bump version to v0.1.4.1

- Add robots.txt with admin/API blocking
- Add dynamic sitemap.xml with static pages and genre pages
- Implement full meta tags (Open Graph, Twitter Cards, Canonical, Alternates)
- Add SEO helper functions for domain detection and URL generation
- Add generateMetadata to all pages (homepage, about, genre, special)
- Support automatic domain detection for hoerdle.de and hördle.de
- Add SEO configuration to lib/config.ts

+# Plausible Analytics Konfiguration
+
+## Übersicht
+
+Die App verwendet Plausible Analytics für anonyme Nutzungsstatistiken. Die Konfiguration erfolgt über Umgebungsvariablen.
+
+## Konfiguration
+
+### Erforderliche Variablen
+
+**Nur eine Variable ist erforderlich:**
+
+1. **`NEXT_PUBLIC_PLAUSIBLE_SCRIPT_SRC`** (erforderlich)
+   - Die vollständige URL zum Plausible-Script
+   - Beispiel (selbst gehostet): `https://plausible.elpatron.me/js/script.js`
+   - Beispiel (extern): `https://plausible.io/js/script.js`
+
+**Hinweis:** Die Domain wird automatisch aus der Request-Domain erkannt. Beide Domains (`hoerdle.de` und `hördle.de`) werden automatisch getrackt.
+
+### Konfiguration für Docker
+
+Da es sich um **Build-Time Variablen** handelt (NEXT_PUBLIC_*), muss die App neu gebaut werden, wenn diese geändert werden.
+
+#### Schritt 1: Umgebungsvariablen setzen
+
+Erstelle oder bearbeite eine `.env`-Datei im Projektverzeichnis:
+
+```bash
+# Plausible Analytics (Script-URL ist erforderlich)
+NEXT_PUBLIC_PLAUSIBLE_SCRIPT_SRC=https://plausible.elpatron.me/js/script.js
+
+# Die Domain wird automatisch erkannt - keine weitere Konfiguration nötig!
+```
+
+#### Schritt 2: docker-compose.yml konfigurieren
+
+Stelle sicher, dass die Variablen als Build-Args übergeben werden:
+
+```yaml
+services:
+  hoerdle:
+    build:
+      context: .
+      dockerfile: Dockerfile
+      args:
+        NEXT_PUBLIC_PLAUSIBLE_SCRIPT_SRC: ${NEXT_PUBLIC_PLAUSIBLE_SCRIPT_SRC}
+```
+
+Die `docker-compose.example.yml` enthält bereits diese Konfiguration.
+
+#### Schritt 3: App neu bauen
+
+**WICHTIG:** Nach Änderung der Plausible-Variablen muss die App neu gebaut werden:
+
+```bash
+docker compose build --no-cache
+docker compose up -d
+```
+
+Oder mit dem Deploy-Script:
+
+```bash
+./scripts/deploy.sh
+```
+
+### Konfiguration für beide Domains
+
+Die App unterstützt **automatisches Tracking** für beide Domains (`hoerdle.de` und `hördle.de`). Die Domain wird automatisch aus dem Request-Header ausgelesen und entsprechend in Plausible getrackt.
+
+#### Automatisches Domain-Tracking
+
+**Standard-Verhalten:** Die App erkennt automatisch, welche Domain aufgerufen wurde, und setzt die entsprechende `data-domain` im Plausible-Script:
+- `https://hoerdle.de/*` → `data-domain="hoerdle.de"`
+- `https://hördle.de/*` → `data-domain="hördle.de"`
+
+#### In Plausible konfigurieren
+
+Du hast zwei Optionen:
+
+##### Option 1: Beide Domains als separate Sites (separate Statistiken) - Empfohlen für getrenntes Tracking
+
+1. Erstelle in Plausible zwei separate Sites:
+   - `hoerdle.de`
+   - `hördle.de`
+
+2. Fertig! Die App trackt automatisch die richtige Domain.
+
+**Vorteil:** Separate Statistiken für jede Domain.
+
+##### Option 2: Beide Domains als Aliase für eine Site (gemeinsame Statistiken)
+
+1. Erstelle in Plausible eine Site: `hoerdle.de`
+2. Füge `hördle.de` als Alias hinzu (in den Site-Einstellungen)
+
+3. Fertig! Die App trackt automatisch die richtige Domain, und Plausible behandelt beide als Aliase für die gleiche Site.
+
+**Hinweis:** Du musst nichts zusätzlich konfigurieren. Die App trackt automatisch `hoerdle.de` oder `hördle.de` basierend auf der Request-Domain, und Plausible erkennt beide als Aliase.
+
+**Vorteil:** Gemeinsame Statistiken für beide Domains in einer Site.
+
+#### Empfehlung
+
+Für separate Statistiken: **Option 1** (automatisches Tracking)
+Für gemeinsame Statistiken: **Option 2** (Aliase in Plausible)
+
+### Automatische CSP-Anpassung
+
+Die Content Security Policy (CSP) in `proxy.ts` wird automatisch an die konfigurierte Plausible-URL angepasst. Die Domain wird automatisch aus der Script-URL extrahiert.
+
+### Prüfen der Konfiguration
+
+Nach dem Neubau kannst du prüfen, ob Plausible korrekt geladen wird:
+
+1. **Browser-Entwicklertools öffnen**
+   - Network-Tab: Suche nach dem Plausible-Script
+   - Console: Prüfe auf Fehler
+
+2. **Prüfe die Meta-Tags**
+   ```html
+   <script defer data-domain="hoerdle.de" src="https://plausible.elpatron.me/js/script.js"></script>
+   ```
+
+3. **Prüfe Plausible-Dashboard**
+   - Öffne dein Plausible-Dashboard
+   - Prüfe, ob Daten ankommen
+
+### Troubleshooting
+
+#### Plausible wird nicht geladen
+
+- Prüfe, ob die Umgebungsvariablen korrekt gesetzt sind
+- Prüfe, ob die App neu gebaut wurde (Build-Time Variablen!)
+- Prüfe Browser-Console auf CSP-Fehler
+
+#### CSP blockiert Plausible
+
+Die CSP sollte automatisch angepasst werden. Falls Probleme auftreten:
+- Prüfe, ob `NEXT_PUBLIC_PLAUSIBLE_SCRIPT_SRC` korrekt gesetzt ist
+- Prüfe die Logs des Containers
+
+#### Daten werden nicht in Plausible angezeigt
+
+- Prüfe, ob die Domain in Plausible als Site konfiguriert ist
+- Prüfe, ob `data-domain` Attribut mit der konfigurierten Domain übereinstimmt
+- Prüfe Browser-Console auf Fehler beim Laden des Scripts
+
+### Beispiel-Konfiguration
+
+#### Für selbst gehostetes Plausible:
+
+```bash
+NEXT_PUBLIC_PLAUSIBLE_SCRIPT_SRC=https://plausible.elpatron.me/js/script.js
+```
+
+#### Für Plausible.io (extern):
+
+```bash
+NEXT_PUBLIC_PLAUSIBLE_SCRIPT_SRC=https://plausible.io/js/script.js
+```
+
+**Hinweis:** Die Domain wird automatisch aus der Request-Domain erkannt - keine weitere Konfiguration nötig!
