Services overview

Engine features are split into services (id + lifetime + optional InvokeFunction API). Storage uses the shared Persistent and Ephemeral branches; each service writes top-level keys under those branches (not nested under the service id unless noted).

• Permanent services — Live for the whole session; menus, settings, input snapshot, theme, audio, etc.
• Ephemeral services — Created per run; currency, shop, boons, seed, timers, etc.

For cross-service JSON calls, see Invocations.
