+              Streaming above 1080p or 60 fps requires significant client-side CPU/GPU encoding
+              power and can saturate server bandwidth, especially when streams are routed through
+              TURN. High-end configurations (e.g., 4K at 120 fps) can require up to 45 Mbps per
+              active stream. Ensure your infrastructure can handle this load before enabling these
+              options for all users.
