Ability to Migrate Layout and Theme Settings Between Production and Sandbox (Both Directions)

Users should be able to synchronize UI settings from Production to Sandbox and vice versa, depending on their workflow.

Please provide one or more of the following capabilities :

• Export/Import of layout and theme settings
• One-click synchronization between Production and Sandbox (in both directions)
• Bidirectional migration of appearance-related settings (Production → Sandbox and Sandbox → Production)
• API support for backing up and restoring these settings
