   Supplied horizontal lockup (6251×1459 ≈ 4.28:1). Height is the control; width
   follows the aspect ratio, so the intrinsic width/height attrs never reserve a
   wrong box. Header art has an ink wordmark for paper; footer art is all white.

   48px is not arbitrary: nav.primary has 10px padding top and bottom, and the
   approved design's nav measures 68px. 10 + 48 + 10 = 68 — the lockup swap keeps
   the header exactly the height it was. */
