+
+/// Global settings manager providing centralized access to all setting groups.
+///
+/// The [Settings] class serves as the main entry point for the settings framework,
+/// offering static methods for registration, initialization, and access to settings
+/// across your entire application. It manages multiple [SettingsGroup] instances and
+/// provides both individual and batch operations.
+///
+/// ## Overview
+///
+/// The settings framework follows a hierarchical structure:
+/// ```
+/// Settings (Global Manager)
+/// │
+/// ├── SettingsGroup (Group: "game")
+/// │   ├── BoolSetting ("soundEnabled")
+/// │   └── DoubleSetting ("volume")
+/// │
+/// └── SettingsGroup (Group: "ui")
+///     ├── StringSetting ("theme")
+///     └── IntSetting ("fontSize")
+/// ```
+///
+/// ## Usage Pattern
+///
+/// ```dart
+/// // 1. Define your setting groups
+/// final gameSettings = SettingsGroup(
+///   key: 'game',
+///   items: [
+///     BoolSetting(key: 'soundEnabled', defaultValue: true),
+///     DoubleSetting(key: 'volume', defaultValue: 0.8),
+///   ],
+/// );
+///
+/// final uiSettings = SettingsGroup(
+///   key: 'ui',
+///   items: [
+///     StringSetting(key: 'theme', defaultValue: 'light'),
+///     IntSetting(key: 'fontSize', defaultValue: 14),
+///   ],
+/// );
+///
+/// // 2. Register all groups
+/// Settings.register(gameSettings);
+/// Settings.register(uiSettings);
+///
+/// // 3. Initialize the entire settings system
+/// await Settings.init();
+///
+/// // 4. Access settings using dot notation
+/// bool soundEnabled = Settings.getBool('game.soundEnabled');
+/// String theme = Settings.getString('ui.theme');
+///
+/// // 5. Modify settings with automatic validation
+/// await Settings.setBool('game.soundEnabled', false);
+/// await Settings.setString('ui.theme', 'dark');
+///
+/// // 6. Batch operations for efficiency
+/// await Settings.setMultiple({
+///   'game.volume': 0.5,
+///   'ui.fontSize': 16,
+/// });
+///
+/// // 7. Reset operations
+/// await Settings.resetSetting('game.volume'); // Reset single setting
+/// await Settings.resetGroup('ui');            // Reset entire group
+/// await Settings.resetAll();                  // Reset everything
+/// ```
+///
+/// ## Storage Key Format
+///
+/// Settings are stored using a namespaced key format: `groupKey.settingKey`
+/// - `game.soundEnabled` → boolean setting in the game group
+/// - `ui.theme` → string setting in the ui group
+/// - `network.timeout` → integer setting in the network group
+///
+/// This prevents key conflicts between different setting groups and provides
+/// logical organization of related settings.
+class Settings {
+  /// Internal registry of all settings groups keyed by their group names.
+  ///
+  /// This map stores all registered [SettingsGroup] instances, providing
+  /// fast lookup by group key. Groups must be registered before use.
+  static final Map<String, SettingsGroup> _settings = {};
+
+  /// Initializes all registered settings groups concurrently.
+  ///
+  /// This method waits for all registered settings groups to complete their
+  /// asynchronous initialization. It's essential to call this method before
+  /// accessing any setting values to ensure they've been loaded from storage.
+  ///
+  /// The initialization process:
+  /// 1. Waits for the underlying SharedPreferences to be ready
+  /// 2. Loads existing values from storage for each setting
+  /// 3. Creates default values for settings that don't exist yet
+  /// 4. Marks all groups as ready for synchronous access
+  ///
+  /// Returns: Future that completes when all settings are initialized
+  ///
+  /// Throws: Exception if any settings group fails to initialize
+  ///
+  /// Example:
+  /// ```dart
+  /// // Register your settings groups first
+  /// Settings.register(gameSettings);
+  /// Settings.register(uiSettings);
+  ///
+  /// // Then initialize everything
+  /// await Settings.init();
+  ///
