Adds an independently buildable onboarding/ TypeScript owner for the branded setup and guided local recording lesson. The React contribution and controller consume Record's public capability contract through injection; Onboarding owns progress, resume/defer, practice attribution and manual paste confirmation. Record #674 is merged, and current main is integrated.

The complete fixture-driven lesson covers color choice and animation, permissions, shortcuts, scoped local-only admission, screen/whiteboard ink, save/copy, manual paste and confirmed opening of the exact saved artifact. Delayed provider readback, stale captures/responses, persistence conflicts, unknown publication, cancellation, reservation cleanup and reconnect are covered. The public Record confirmation helper is bundled into the artifact; there is no runtime dependency on a sibling source tree.

Validation: 33 tests including mounted end-to-end and button interactions; strict source/test typechecks; build; clean component-delivery build and packed runtime consumer; diff checks. Independent read-only re-review approved code candidate c87b34d after reproducing typecheck and all tests. The later commit only updates dependency/readback documentation. Normal guarded push checks apply.

This slice supplies fixture-tested consumer behavior, not installed adoption. Production Record permission/shortcut/pen/stroke/reservation/delivery producers, confirmed artifact-open evidence, a transactional progress adapter and host routing still require implementation and affected native proof. Existing installed routing, sole config writer, Preview releases and #658 remain unchanged. The new delivery descriptor registers an independent library artifact; existing conservative feature-push selection still includes broad root checks for this new owner.
