Editor/Inspector/IExpandStateStore.cs
Interface for storing UI expand/collapse state in the RazorDesigner inspector. It exposes Get to retrieve a saved boolean state with a fallback, and Set to record a key's expanded state.
using System.Collections.Generic;
namespace Grains.RazorDesigner.Inspector;
public interface IExpandStateStore
{
// Returns the saved expand state for `key`, or `fallback` if not present.
bool Get( string key, bool fallback );
// Records that `key`'s section is `expanded`. Persisted at the store's discretion.
void Set( string key, bool expanded );
}
