-A Bevy game, editable in the [jackdaw](https://github.com/jbuehler23/jackdaw) editor.
-
-- `cargo run` plays the game standalone; no editor required.
-- Open the folder in jackdaw to author scenes, then hit Play. The
-  editor builds its own artifacts into `.jackdaw/` (gitignored) and
-  never modifies your manifest or lockfile.
-- Gameplay lives in `src/lib.rs` (`GamePlugin`); authored scenes live
-  in `assets/*.bsn`.
-- Components you derive `Reflect` on appear in the editor's inspector
-  automatically; no registration code is needed.

 ## Direct P2P Debugging
 
-The debug match can be run as two processes over UDP. Each process uses a
-different local port, and remote player declarations are keyed by the GGRS
-player handle:

 # Process 1 owns player 0 and listens on 7000.
 cargo run -- --debug-match --players 2 --local-port 7000 \

-Without `--net-player`, all requested players are local. This direct UDP
-configuration is intentionally separate from match selection so a future
-lobby provider can supply the same player roles and addresses.
