   OAK TREE — RELAUNCH, glass seams. Loads AFTER relaunch.css.
   One device carries the whole branch: a plate of opaque glass laid ACROSS
   the seam between two pictures. It dips into the bottom of the picture
   above and the top of the one below, and a text-width feathered spacer
   hangs beneath it, so the plate IS the transition. Same frosted recipe as
   the rules cards on the range photographs.
     .bsec    homepage banners (click to expand)
     .gplate  any other panel that sits on a seam (range spec panels, the
              standing week on the events page)
