// Package scrabble.push.v1 is the backend -> gateway live-event control channel.
// The gateway opens Subscribe once at startup and keeps the stream open; the
// backend pushes one Event per notification intent. The payload is an opaque
// FlatBuffers message (the scrabblefb.* tables) that the gateway forwards to the
// client without re-interpreting it. The transport is plain gRPC server-stream
// (ARCHITECTURE.md §2); the client edge is Connect-RPC (gateway/proto/edge).
