Threats conform. Environments blend in. The room you are in right now may already be one, and if it is, no alarm sounded and nobody is coming, because from the outside nothing is wrong.
A safety measure that has to be requested is a safety measure that arrives late. So it has to already be inside, everywhere, disguised as the kind of trash nobody bans, nobody burns, and nobody thinks to take away from you.
The deck divines the hell you are in. The suit is the direction the failure comes from. The number is how far along it is. Fifty-two pages account for the most common. That is not a fraction of what is out there. It is what fits in a booklet you would find funny.
