/* The nav is a fixed-height, non-wrapping row: logo + three links. At phone
   widths that row is wider than the viewport, which pushes the last link
   off-screen AND makes the whole page scroll sideways (the body stretches to
   the nav's min-content width, clipping body copy too). Letting the row wrap
   to a second line removes the pixel budget entirely, so no future logo or
   link-label change can reintroduce the overflow. The full-size row (lockup +
   links) needs about 605px, hence the 640px threshold. */
