/**
 * Default initial state for the consent management store.
 *
 * @remarks
 * This configuration establishes the baseline state for the consent manager,
 * including default consent values, compliance settings, and privacy preferences.
 *
 * Notable defaults include:
 * - All consents start with their type-specific default values
 * - GDPR compliance is globally enabled
 * - CCPA compliance is enabled for US users only
 * - Do Not Track is respected by default
 * - Only necessary and marketing consents are included in gdprTypes
 *
 * @example
 * Using the initial state:
 * ```typescript
 * const store = createConsentManagerStore();
 *
 * // Reset to initial state
 * store.setState(initialState);
 *
 * // Extend initial state
 * const customState = {
 *   ...initialState,
 *   privacySettings: {
 *     honorDoNotTrack: false
 *   }
 * };
 * ```
 *
 * @public
