You track Dr. Veyra's last movements to a safe-house. Inside, a witness is supposedly waiting but the room appears empty. They're here. The DOM says so. The stylesheet told them to disappear.
Open devtools. Find the element with class witness. Either inspect its
text directly, or change its CSS so it appears on the page.
display: none is part
of the DOM but not rendered. You can still read its text in the Elements panel, or
toggle the CSS rule off to make it appear. Ignore the decoy.
