Field	Required	Rules
`schemaVersion`	Yes	Must be `1`
`name`	Yes	1–80 characters
`entrypoint`	Yes	Relative `*.html` path. No leading `/`, no `..`
`multiplayer`	No	If present, all four subfields are required
`multiplayer.enabled`		`true` or `false`
`multiplayer.authority`		`"host"` or `"server"`. `"server"` requires `step`
`multiplayer.maxPlayers`		Integer 1–16
`multiplayer.tickRate`		Integer 1–30
`networkAllowlist`	No	Up to 10 absolute URIs. Default `[]`

tickRate is a deployment-time room-loop hint. Do not copy a realtime snapshotHz into it. Realtime publish is a separate ceiling (default 30 Hz, cap 100 Hz) set on the room.

npx lokiplay init and connect write this file if it is missing. Default maxPlayers is 8 and tickRate is 30. Default authority is "host". "server" is valid only with step (abiVersion, modulePath, sha256).

A new manifest does nothing to the live game until you ship. The play link keeps serving the last activated release.
