+## YouTube IP-Block / Proxy
+
+YouTube blockiert oft Server-IPs (Hetzner, AWS, …). Optional in `.env`:
+
+```bash
+# Statischer Proxy (z.B. aus Webshare „Proxy Server“ / Dashboard-Zeile)
+YOUTUBE_PROXY=http://USER:PASS@HOST:PORT
+```
+
+Für yt-dlp-Fallback und VTT-Downloads wird dieselbe URL genutzt.
+
+**Webshare-Hinweis:** Der kostenlose Tier und „Proxy Server“ (einzelne IP wie im Dashboard) funktionieren *manchmal* für wenige Recaps pro Tag — laut `youtube-transcript-api` aber unzuverlässig. Rotating **Residential** (kostenpflichtig) ist die robuste Lösung:
+
+```bash
+WEBSHARE_PROXY_USERNAME=...
+WEBSHARE_PROXY_PASSWORD=...
+WEBSHARE_PROXY_LOCATIONS=de
+```
+
+Öffentliche Gratis-Proxy-Listen: nein (langsam, unsicher, meist schon gebannt).
