Wire horizontal swipe into the mobile tap-zone overlay (single mode only, so continuous mode keeps native vertical scroll). A leftward swipe past the threshold turns to the next page, rightward to the previous; a mostly- vertical drag is ignored so panning a tall page never turns it. The gesture suppresses the synthesized zone tap so it doesn't double-fire. Swipe classification is a pure, unit-tested helper; e2e drives real touch pointer events for horizontal (both directions) and vertical cases.
