A job title describes the task. A named category describes the judgment underneath it — the thing that survives when competent output is abundant and cheap. One is a line on an invoice. The other is the reason the invoice is that size.
Every category below was read out of a real moodboard using seven lenses, applied in order. None of them existed as a job anyone could apply for. All of them are now the thing their owner is known for. Read them for the shape, not the label — yours will not be on this page, because it has not been named yet.
