Dissect the HTTP/3 over QUIC handshake byte-by-byte. Visualise the 1-RTT fresh handshake, session-ticket resumption, and 0-RTT early-data scenarios, with sequence diagrams, per-packet field layouts, the Retry packet, and a side-by-side comparison against TCP + TLS 1.3. Built for interview prep, protocol learning, and performance engineering.
