/* Book Nook — one stylesheet, no build step.
   Order: fonts, tokens (dark is the default, light is a choice), base, shell, components,
   signature moments (library, shelf, review stack, capture, queue, landing), view transitions,
   reduced motion. Modern CSS carries the design: @property, color-mix, container queries,
   scroll-driven animations, 3D transforms, view transitions. */
