/* AETHELGARD world site.
   Layout: a hub and eight chapters. Every chapter opens on a full-bleed plate (an image slot),
   then reads in a two-column body: a sticky "on this page" rail and a 68ch text column,
   with figures allowed to break out wide. Each chapter is graded like the film: space, drift,
   crown, aerie, floor, shelf. */
