      PluginReactLynxOptions.firstScreenSyncTiming property

      This flag controls when MainThread (Lepus) transfers control to Background after the first screen

      This flag has three options:

      "immediately": Transfer immediately

      "jsReady": Transfer when background (JS Runtime) is ready

      "manual": Transfer when the business calls the markFirstScreenSyncReady() API exported by @lynx-js/react, so the handover timing is fully controlled by the user

      After handing over control, MainThread (Lepus) runtime can no longer respond to data updates, and data updates will be forwarded to background (JS Runtime) and processed __asynchronously__

      Signature:

      firstScreenSyncTiming?: 'immediately' | 'jsReady' | 'manual';

      Default Value

      "immediately"
