💡 What: Replaced JSON.parse(JSON.stringify()) with native structuredClone() as any for deep cloning the settings object.
🎯 Why: JSON.parse(JSON.stringify()) is slower due to string serialization/deserialization and cannot handle complex types. structuredClone is the native, more efficient way to deep copy objects.
📊 Impact: Faster deep cloning, saving CPU cycles on the main thread during user input and saves, leading to smoother interactions in the Settings Editor.
🔬 Measurement: Can be measured by profiling the update and handleSave functions in the DevTools Performance tab. structuredClone should execute in less time than the JSON serialization cycle.
