Drag, flick and tap-vs-scroll now live on the scrollX/scrollY flag in ui.lua, so any scroll box pans with no app code. tree.hit returns the deepest node by geometry and dispatch bubbles to the nearest handler, dropping the now-unused CAPTURE flag. keyboard moves in as ui.keyboard, and embed compiles nested lib dirs to dotted module names.
