Add intermediate breakpoints (960px, 1024px, 900px, 640px, 600px) for tablets and fold
devices across all 12 rApp components. Add touch-action: manipulation and
-webkit-tap-highlight-color to eliminate 300ms tap delay. Fix undersized tap targets
(<36px) in rtasks, rfiles, rinbox, and rcart. Replace HTML5 drag API with pointer events
in rtasks kanban and rchoices ranking for touch/pen/mouse parity. Replace mouseenter/
mouseleave with pointerenter/pointerleave in rchoices spider chart with click toggle.
