We swept every venture page for four keyboard and zoom problems: positive tabindex, user-scalable=no or maximum-scale=1 viewports, autofocus, and outline: none rules. The first three found nothing. Three pages remove outlines, and two of them replace the ring with a visible stroke on :focus-visible (which-job-first, shed-designer).
The third, dupehound, made its result rows focusable (tabindex="0") and removed the outline, leaving only a pale background tint. Someone tabbing through the clone list could not easily see which row was selected. The rule now draws a 2 px outline on :focus-visible, and a page test guards it.
This was a one-page finding from a sweep of about 1,300 pages, so the earlier sweeps were right that the catalogue is mostly clean.
