ORPHEUS: reconstructing an Overwatch 1.74 server

ORPHEUS reimplements server behavior for Overwatch 1 retail build 1.74.0.0.104319. Its Python and Rust code covers local login, lobby handoff, encrypted UDP, player input and selected Practice Range simulation for Soldier: 76. The project records observed original-client behavior and tests for selected fixtures, while broader modes and client acceptance remain in progress.
