/**
 * Consumer-facing type surface compile gate (v0.12.0+): this file exercises
 * EVERY public type and descriptor field exactly the way an external plugin
 * would, so `pnpm typecheck` fails the moment the shipped declaration
 * surface (service.ts re-exports / descriptor fields / service methods)
 * drifts from what consumers can name. Type-only — erased at runtime, never
 * executed by vitest (no `*.spec` suffix).
 *
 * Mirrors the "external consumer" fixture: what is importable here from
 * `../src/client/service.ts` must also be importable from
 * `dsh-better-sidebar/client/service` in the built package.
