# Scenarios

The whole XWUINavMenu surface driven from ONE json spec - every config axis and every item feature in a single mount, so a change can be judged against all of them at once instead of one example per combination. SPEC.axes drives the control strip: add a value there and a button for it appears, no wiring. SPEC.data exercises the item shape end to end - icons and icon-less entries, href and handler-only, disabled leaf, disabled PARENT, dividers, and three levels of nesting.
