What this user agent did

Directly-referenced assets:

✓ fetched CSS ✓ fetched JS ✓ fetched image ✓ fetched font (HTML)

Document-level link hints:

✗ fetched favicon ✗ fetched apple-touch-icon ✗ fetched web manifest ✓ fetched preload ✓ fetched prefetch

Social embed (Open Graph / Twitter card images):

✗ fetched og:image ✗ fetched twitter:image
