A field guide, not a shrine.

ONLY 3 LEFT™ documents deceptive UX patterns as interface specimens: named, classified, explained, and kept at a professional distance.

The goal is educational. Developers, designers, product teams, and curious readers should be able to recognize the mechanics, understand why they work, and choose better alternatives.

The tone is deliberately dry because manipulation often arrives in cheerful microcopy. The critique is serious; the wink is evidence handling.
