/* Naatjes Concrete — archetype G, single screen with anchored panels.
   The last unused archetype in the ledger. One viewport tall; the nav swaps
   panels via :target rather than scrolling, because this business has four
   service lines and little else, and a long page would be padding.

   No JavaScript: :target does the switching, and with no fragment in the URL
   the first panel shows by default. On a phone the panels simply stack, since
   viewport-height tricks and mobile browser chrome do not get along. */
