-/**
- * Preview Mode Host Example
- *
- * Demonstrates how to run the platform in "preview" mode.
- * When `mode` is set to `'preview'`, the kernel signals the frontend to:
- * - Skip login/registration screens
- * - Automatically simulate an admin identity
- * - Display a preview-mode banner to the user
- *
- * Use this for marketplace demos, app showcases, or onboarding
- * tours where visitors should explore the system without signing up.
- *
- * ## Usage
- *
- * Set the `OS_MODE` environment variable to `preview` at boot:
- *
- * ```bash
- * OS_MODE=preview pnpm dev
- * ```
- *
- * Or use this stack definition directly as a starting point.
- *
- * ## KernelContext (created by the Runtime at boot)
- *
- * ```ts
- * import { KernelContextSchema } from '@objectstack/spec/kernel';
- *
- * const ctx = KernelContextSchema.parse({
- *   instanceId: '550e8400-e29b-41d4-a716-446655440000',
- *   mode: 'preview',
- *   version: '1.0.0',
- *   cwd: process.cwd(),
- *   startTime: Date.now(),
- *   previewMode: {
- *     autoLogin: true,
- *     simulatedRole: 'admin',
- *     simulatedUserName: 'Demo Admin',
- *     readOnly: false,
- *     bannerMessage: 'You are exploring a demo — data will be reset periodically.',
- *   },
- * });
- * ```
