The finger-follow edge gesture starting at the very left edge collided with iOS's own edge-swipe,
which fires touchcancel instead of touchend, so cleanup never ran and .content stayed transformed +
chat-dragging stuck on top -> bottom nav hidden and all clicks blocked. Back to the safe release-based
swipe (still gets showWelcome's parallax slide). Keyboard --kb inset, #7 no-dance, #8 image swipe kept.
