		 * Centralized reactive store for theme style settings in the Form Builder.
		 *
		 * Provides a simple pub/sub mechanism to track and respond to setting changes.
		 * Automatically initializes its state from all inputs/selects matching `name="settings[themes][...]"`.
		 *
		 * Usage examples:
		 *
		 * // Subscribe to a specific setting change.
		 * app.store.subscribe('buttonTextColor', (value) => {
		 * console.log('Button text color changed to:', value);
		 * } );
		 *
		 * // Subscribe to all setting changes.
		 * app.store.subscribeAll(( value, key) => {
		 * console.log( Setting ${ key } changed to:`, value);
		 * });
		 *
		 * // Get current value.
		 * const padding = app.store.get('containerPadding');
		 *
		 * // Manually update a setting (will trigger listeners).
		 * // Use the 3rd argument as 'true' to set in a 'silent' mode when state and input will update,
		 * // but no listeners will be run.
		 * app.store.set('fieldSize', 'medium');
		 *
		 * @since 1.9.7
		 *
		 * @type {Object}
		 * @property {Function} get          Get current value of a setting by key.
		 * @property {Function} set          Set value of a setting by key and notify listeners.
		 * @property {Function} subscribe    Subscribe to a specific setting change: (key, callback) => void
		 * @property {Function} subscribeAll Subscribe to all setting changes: (callback) => void
		 * @property {Function} initFromDOM  Initialize the store from DOM inputs/selects.
		 * @property {Object}   state        Raw internal state object (mostly for debugging).
