 * @objectstack/spec
 * 
 * ObjectStack Protocol & Specification
 * 
 * This package does NOT export types at the root level to prevent naming conflicts.
 * Please use namespaced imports or subpath imports.
 * 
 * ## Import Styles
 * 
 * ### Style 1: Namespace Imports from Root
 * ```typescript
 * import { Data, UI, System, Auth, AI, API } from '@objectstack/spec';
 * 
 * const field: Data.Field = { name: 'task_name', type: 'text' };
 * const user: Auth.User = { id: 'u1', email: 'user@example.com' };
 * ```
 * 
 * ### Style 2: Namespace Imports via Subpath
 * ```typescript
 * import * as Data from '@objectstack/spec/data';
 * import * as UI from '@objectstack/spec/ui';
 * import * as System from '@objectstack/spec/system';
 * import * as Auth from '@objectstack/spec/auth';
 * 
 * const field: Data.Field = { name: 'task_name', type: 'text' };
 * const user: Auth.User = { id: 'u1', email: 'user@example.com' };
 * ```
 * 
 * ### Style 3: Direct Subpath Imports
 * ```typescript
 * import { Field, FieldType } from '@objectstack/spec/data';
 * import { User, Session } from '@objectstack/spec/auth';
 * 
 * const field: Field = { name: 'task_name', type: 'text' };
 * const user: User = { id: 'u1', email: 'user@example.com' };
 * ```

// ============================================================================
// NAMESPACE EXPORTS — REMOVED
// ============================================================================
// `export * as Namespace from './sub'` is NOT tree-shakeable in Node ESM —
// every subdomain (16 of them, ~400 Zod schema closures) is force-evaluated
// on the first `import` of `@objectstack/spec`, even when consumers only
// touch one namespace. This caused ~1.2GB RSS bloat in `@objectstack/objectos`.
//
// Use subpath imports instead:
//   import * as Data from '@objectstack/spec/data';
//   import { Field } from '@objectstack/spec/data';
//
// Enforced by the `no-restricted-imports` ESLint rule.
