   The flipbook's own pixel size is computed in script.js
   (pageSize()), which measures the real #app-bar/#book-nav
   height at runtime and shrinks the book so it always fits
   the viewport — no scrolling needed to reach Prev/Next.
   These rules only handle chrome (bar/nav/touch targets);
   they intentionally avoid forcing tall min-heights that
   would fight that calculation.
