Four layout directions for a version of the UK liver waiting list simulator that someone with no prior knowledge of liver allocation could use: adjust a few things, see the effect, compare options without being overwhelmed. Each direction has a desktop page and a phone mock-up. They are static mock-ups on the existing engine's premise; nothing here runs a simulation.
Five plain-language levers on the left; one picture on the right: 100 people a year after joining the list, with the UK figure beside each count. Pin as A, change something, and a compare strip appears below.
Most direct for "adjust and see". Animation is a button, not the landing view.
A gallery of six questions, each changing one thing with two or three preset versions shown side by side, a one-paragraph reading, a "why?" and range bars. "Ask your own question" leads to free play.
Lowest barrier for a first visit; matches the "change one thing" approach to comparisons.
Six chapters down one page: the list, livers arrive, a rule decides, a year later, your choices against the UK now, go further. Each adds one idea and one control, and choices carry through.
Teaches the system while it is used; overlaps with the existing introduction tour.
World A is the UK now; world B carries one change. Same compact settings, a mini list view each, the outcome pictures, and a central spine of differences, with paired runs.
Comparison is the page; the clearest demonstration of "same people, same livers".
