//! Example: Delete assets
//!
//! This example demonstrates how to delete assets from Immich.
//!
//! WARNING: This will actually delete photos. Use with caution!
//!
//! This example uses environment variables for configuration:
//! - IMMICH_URL: The Immich server URL (defaults to http://localhost:2283)
//! - IMMICH_API_KEY: Your API key (required)
//!
//! IMPORTANT: Run this against a test instance only. This operation permanently
//! removes assets from the server.
