The room for the people who build, fix, and keep the thing running — the electricians, the engineers, the tradespeople, the ones whose merit is on the floor, not on a diploma. Same idea underneath all of it: prove what you did, and the résumé takes care of itself.
Still filling in the floor — the medical, psychology, creative, and marketing bundles come in as their stories land, each opening its own OPA college. New trades slot in as cards; the door never has to change.
