⚙️ Detailed Breakdown

1. WebTransport + FEC

🔧 Architecture

Runs over HTTP/3, which runs over QUIC, meaning:

You get QUIC’s low latency + UDP behavior.
But exposed via a web-friendly API (WebTransportSession, sendDatagram(), etc.).
Add FEC (Forward Error Correction) in user space, flexible & pluggable.

⚡ Performance

QUIC’s congestion control and loss recovery are retained.
Slight (2–5%) overhead due to HTTP/3 wrapping.
FEC gives you lossless transfers even on 30–40% drop links.
Prioritized streams = real-time metadata unaffected by heavy data transfer.

Net result: ~95% of pure QUIC throughput, with massive real-world resilience boost.
