E2E Test Plan

Setup:
- Log in with a user that has appropriate permissions
- Navigate to /triage/artifacts/:artifactId
- Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
Core verification:
- Verify the editor/studio loads with editable content or empty template
- Verify changes can be saved and persisted
- Verify validation errors are displayed for invalid input
Edge cases:
- Verify graceful handling when backend API is unavailable (error state)
- Verify responsive layout at different viewport sizes
- Verify accessibility (keyboard navigation, screen reader labels, ARIA attributes)
