// this module compiles with a Java-25 toolchain. The toolchain block makes that explicit
// and self-enforcing: Gradle uses a detected JDK 25 whichever JDK runs Gradle, and fails
// loudly if none is present. The shared codec is plain Java-17 source, which 25 compiles
// forward-compatibly.

// The lobby is a PURE UI face (spec §12): it speaks only the felis:control
// plugin-message channel and never holds a felis-api token or talks to felis-api
// directly. We enforce that physically here — the shared source root is on the
// path, but the include filter ships ONLY the paper package and the three codec
// files (Control + ControlFrame + Json). FelisApiClient, LinkClient and the token
// config are not compiled in at all, so the lobby cannot reach the API even by
// mistake. If a codec class grows a new dependency, compilation fails loudly here
// rather than silently widening the lobby's reach.
