summary
Gives concrete UI changes: replace dividers with spacing, group related fields and color-code tracks, add a bold colored tag to highlight a recommended plan, and limit choices to three or four with progressive disclosure; demonstrates a live QR word‑cloud and quick memory tests that show primacy/recency and the isolation effect making single options memorable; cites Johnson and Goldstein 2003 where opt‑out defaults push organ‑donor rates above 99% and recommends using opt-out default or marked toggles deliberately.
