+## Self-Healing Fallback (v2.3.0)
+
+When Cloudflare blocks streaming requests, the API automatically tries fallback methods:
+- **Direct** → Mirror rotation across 4 domains (miruro.to, miruro.ru, miruro.bz, miruro.tv)
+- **ScraperAPI** → Free proxy bypass (1K req/month, set `SCRAPER_API_KEY` env var)
+- **FlareSolverr** → Self-hosted browser proxy for full Cloudflare bypass
