Extra Configuration
The content arrays in config.json, handing the shutdown to your framework.
Extra integration
fxmanifest.lua sets loadscreen_manual_shutdown 'yes', so client/main.lua owns when the screen goes away. Left alone it dismisses once the session has started and Loading.MinDisplayMs has elapsed, with Loading.SafetyTimeoutMs as a hard backstop.
An explicit request bypasses MinDisplayMs but still gets the fade, so the handover stays smooth. Calling it more than once is harmless.
