          /* HITL approval card — mobile readability pass.
             Default desktop layout cramped a monospace key + an
             inline "0.0040 → 0.0062" pair into a 360px card; the
             value column kept ellipsising the keys and the digits
             read as illegible at 13px. Mobile rebuilds the card so
             each diff row stacks (key on top, before-after value
             below), fonts bump up, and the action buttons sit on
             their own row each. */
