/* Homepage hero: the display rack (rack.js), in place of the website kiosk.

   Printed pieces set out against the dawn sky in two rows, with nothing
   holding them: site maps on top, rack cards and brochures below, all to one
   scale (rack.js sets --u, pixels per inch, and each piece's size in inches;
   the pieces come from the editor's Home Page tab, via cms_rack()). Each sits
   in a "pocket", its place in the row.
   Pointing at a piece raises it slightly; clicking brings it forward, larger.
   Wide screens show what fits; narrow ones swipe sideways through them all. */
