1-line CSS: adds touch-action:manipulation + -webkit-tap-highlight-color:transparent to
button/.icon-btn/.send-btn/.approval-btn/[onclick] inside the touch/compact media block
(@media max-width:1399.98px), removing iOS Safari's ~300ms double-tap-zoom delay so taps
fire on first touch. Added a regression test pinning the rule.
