A designer commented on my last post that the 3D hangar only works because every station maps to a real business function. He's right. So this one is pure function.

FRICTION: one signup form, filled twice. Form A is the form everyone actually ships - placeholder-only labels, paste blocked on confirm email, password rules revealed one failure at a time, errors that only appear after you hit submit. Form B is the same six facts, designed right.

The page measures your hand while you fill it - every keystroke, backspace and rage click - then draws your cursor path like a session replay and prints the bill on a receipt.

My own run: 3:35 on Form A, 0:57 on Form B. 3.8x slower, 2 rage clicks, 3 submit attempts. Same person, same fake answers. The only thing that changed was the design.
