/* Service pages pushed the viewport 9px sideways at 320px, and had done since
   before the #24-#28 batch. `.file-actions` already wraps, so the row was never
   the problem: a single button was. `.btn` in site.css is `white-space: nowrap`
   with 24px of side padding, so "Speak to us about wealth planning" measured
   309px against a 280px content box (320px less two 20px gutters) and simply
   stuck out. Padding alone cannot recover 29px — dropping it to 10px still
   leaves the button over — so the label has to be allowed to wrap.

   Below 400px the two buttons stack and each takes the full column, which is
   the honest amount of room they have. `white-space: normal` is what actually
   fixes the overflow; `line-height` is raised from the base 1 because a wrapped
   label at line-height 1 sets solid. Measured after: 0px overflow at 320, 360
   and 390 on all six service pages. */
