Native app target using deep link return and one-time handoff exchange.
Zhmyak Start
Expose only enabled platform targets for the active rollout.
The platform chooser remains a presentation layer. It only switches the target client and forwards the existing flow context into `/handoff` without taking over account or session logic.

Miniapp
