/* =========================================================
   A Book, an Axis — shared stylesheet

   Desktop: fluid layout that fills the viewport. Type stays at a
   fixed readable size; horizontal gaps compress; copy wraps taller;
   decorative images shrink so pages do not scroll.

   Landing is a special case: full-bleed cover image, title locked
   to the visual center, social links locked to the bottom edge.
