/* The Book of Rare Diseases — one stylesheet for every page.
   Shell: the Sept 27 draft redesign (draft-redesign.html): Atkinson Hyperlegible, door rows,
   amber layer gauges, standfirst / surface / layers.
   Components carried from the Sept 22–27 live page (vsi-kit, rd-*) and the Sept 7–11 rooms
   (flags, ladder, short answer, ring, pillars, claims), re-pointed at the redesign tokens through
   the alias block below, so their markup is carried unchanged. */
