3// Runtime `AppConfig` component. Its authored args live in the schema crate
4// (concinnity_asset::app_config); only what the running process needs survives
5// the bake: the state-tree location and the resource budgets. The distribution
6// metadata (name, id, version, author, icon) is read at build / export time
7// from the authored world, so it never ships in the blob.
