You find Dr. Veyra's blueprint pinned to the wall. It looks mostly empty just
a few faint marks. But the stylesheet has been tampered with. Some text has been
given the same color as the background. Some has been dimmed to near-zero
opacity. Some is painted on by a ::after pseudo-element.
Inspect the blueprint. Read the full contents of each line in the Elements panel. Assemble the token from the three fragments.
::after rule.
