 * The aesthetic: dark, atmospheric, prose-forward. Vollkorn serif for
 * body text. Dark translucent panels float over a full-bleed AI
 * atmosphere image. The prose is the surface; everything else gets
 * out of the way.
 *
 * Title screen + chrome share the landing page's palette so the
 * front-cover-then-page-turn experience reads as one piece of work:
 *   void/parchment/cream typography, gold accents, lavender italics.
