Re-ran the CNN homepage rendering investigation with the new default
1920x1080 viewport. F-001 (flex overflow) no longer manifests at this
width, F-007 (nav links) upgraded to Open/High since the >=960px media
query should now match, and F-011 (duplicate badges) regressed. Added
two new findings: F-013 (narrow sidebar grid columns) and F-014
(unsupported :-webkit-full-screen selector).
