     1180px  small laptop  -> hamburger nav, fan diagram becomes 2 columns
     1024px  tablet        -> tighter gutters / section spacing
      768px  large phone   -> single column, smaller type & padding
      480px  phone         -> full-width buttons, compact cards
      360px  small phone   -> final squeeze
