- * The native SharedImage plugin is registered asynchronously by AppDelegate
- * (with its own retry budget), so a fixed startup delay cannot guarantee the
- * plugin is reachable from JS before the first shared-image check. Instead of
- * assuming readiness after an arbitrary sleep, we probe the plugin with a
- * lightweight, read-only hasSharedImage() call and retry for a short bounded
- * period until it responds or the budget is exhausted.
- *
- * This applies ONLY to the very first startup shared-image check. The
- * appStateChange and appUrlOpen paths are intentionally left unchanged.
