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

Second-level follows (proves it parsed the linking file):

✓ followed CSS background-image ✓ followed CSS @font-face ✗ followed manifest icon ✓ followed CSS @import

Frames (does it descend into iframes?):

✓ fetched iframe document ✓ descended into iframe (loaded inner image)

Reporting (a report-only CSP is violated by inline styles; reports can arrive via HTTP headers with no JS, or via in-page beacons):

✓ sent a CSP/Reporting report (any path) ✓ delivered via report-uri/Report-To header (no JS) ✓ delivered via in-page beacon (securitypolicyviolation / ReportingObserver)

Social embed (Open Graph / Twitter card images):

✗ fetched og:image ✗ fetched twitter:image

JavaScript execution:

✓ EXECUTED classic JS ✓ EXECUTED ES module ✓ posted client timing
