   Bulma's .section gives 48px top/bottom and each section also carries a
   40px .placeholder40 at both ends, putting adjacent sections 176px apart.
   This is a concept launch page, so the vertical rhythm is opened up to
   240px between sections. The dark .idn-enterprise band carries no
   placeholders, so it gets the full 120px in padding to match the same
   optical gap. Mobile scales back, matching how .placeholder40 halves. */
