// Author typings for Orca components panels (`"ui": "components"`): the runtime API.
// `orca plugin types` joins this file with orca-components*.d.ts (the catalog) and installs
// types/orca-services.d.ts, which adds `shell`, `files`, `on`, `plugin`, `storage`, `settings` and
// `secrets` to this module. Mirrors src/shared/plugins/declarative/ (checked by
// plugin-declarative-typings.test.ts); host methods are generated from the host API.
