/* Dune — hero

   The plate is a desert at sunset: the sun on the horizon between two ranges,
   a sky burning orange into purple, and rippled dunes below. The camera is
   still and only the clouds drift. Against white type the sky measures only
   2.5-3.5:1, but the shadowed dune down the left edge reads 8-14:1 from
   mid-height down, so the copy sits on the left, centred in the height. The letters carry a soft shadow of their own for the lighter
   sand they cross; nothing is laid over the footage. */
