/**
 * Snapshot Tests for Text-to-CAD API Requests
 *
 * These tests are primarily designed to capture the requests sent to the Text-to-CAD API
 * rather than to verify application behavior. Unlike regular tests, these tests:
 *
 * 1. Don't assert much about the application's response or state changes
 * 2. Focus on setting up specific scenarios and triggering API requests
 * 3. Use the captureTextToCadRequestSnapshot() method to save request payloads to snapshot files
 *
 * The main purpose is to maintain a collection of real-world API request examples that can be:
 * - Used for regression testing the (AI) API
 * - Referenced when making changes to the Text-to-CAD integration, particularly the meta-prompts
 *   the frontend adds to the user's prompt
 *
 * These tests intentionally don't wait for or verify responses, as we're primarily
 * interested in capturing the outgoing requests for documentation and analysis.
 *
