/**
 * E2E Tests for Analytics Dashboards Integration
 *
 * Future Enhancement: Integrate Agent Browser CLI for 95% reliable, deterministic testing
 * - Snapshot-based element references (@e1, @e2, etc.)
 * - Self-healing tests that adapt to UI changes
 * - 95% first-try success rate vs 75-80% for traditional selectors
 *
 * For now, using standard Playwright with graceful fallbacks and URL-based verification
