/**
 * Lighthouse Audit for All Locales
<<<<<<< HEAD
 *
 * Runs Lighthouse performance audits against all locales (de, en, sr)
 * and key pages using Playwright-Lighthouse integration.
 *
 * Usage: node scripts/lighthouse-audit-all-locales.js
 *
 * Requirements:
 * - Dev server running on localhost:3000 (npm run dev)
 * - Chromium installed via Playwright
 *
 * Thresholds:
 * - Performance: 90%
 * - Accessibility: 90%
 * - Best Practices: 90%
 * - SEO: 90%
 *
 * Note: Performance and SEO scores may be lower in development mode.
 * Accessibility and Best Practices should always meet thresholds.

## Executive Summary

This report documents Core Web Vitals (LCP, CLS, INP/TBT) measurements for all three language versions of the portfolio website in both mobile and desktop modes.

### Key Metrics Explained:

- **LCP (Largest Contentful Paint):** Measures loading performance. Good: < 2.5s, Needs Improvement: 2.5-4s, Poor: > 4s
- **CLS (Cumulative Layout Shift):** Measures visual stability. Good: < 0.1, Needs Improvement: 0.1-0.25, Poor: > 0.25
- **INP/TBT (Interaction to Next Paint / Total Blocking Time):** Measures interactivity. TBT Good: < 200ms, INP Good: < 200ms
- **FCP (First Contentful Paint):** Measures perceived load speed. Good: < 1.8s
- **Speed Index:** How quickly content is visually displayed. Good: < 3.4s

## Recommendations Summary

Based on the audit results, here are the key areas for improvement:

### High Priority (Performance Impact)

1. **Largest Contentful Paint (LCP):** Focus on optimizing the hero image and main content loading
2. **Total Blocking Time (TBT):** Reduce JavaScript execution time, consider code splitting
3. **First Contentful Paint (FCP):** Optimize critical rendering path

### Medium Priority (User Experience)

1. **Cumulative Layout Shift (CLS):** Ensure images have explicit dimensions, avoid layout shifts from fonts
2. **Speed Index:** Optimize above-the-fold content delivery

### Common Opportunities Across All Tests
