GitHub labels: Stellar Wave

Drips complexity: Medium (100 points)

Area: Testing

Description

Analytics PDF digest export exists with unit tests, but no e2e verifies the download button in a real browser.

Requirements and Context

CI should catch regressions where export button is disabled or download fails silently.

Suggested Execution

git checkout -b test/e2e-analytics-digest-export

1. Create branch test/e2e-analytics-digest-export
2. Connect mock wallet with positions
3. Navigate to /analytics
4. Click PDF export and assert download event
5. Keep spec under 30s headless
