/* bentwall.com — articles
   The dark room stays: same header, same footer, a dark title band so an
   article opens like every other page. The text itself sits on a lit panel,
   the way wall text does in a gallery, because 1,500 words of light-on-dark
   is tiring to read. Pictures inside an article hang in dark mats, so a work
   looks the same here as it does on the wall.

   Loaded only by article pages, via $bw_head_extra. Everything is scoped
   under .bw-art so nothing here can touch the wall or the other pages. */
