/* Book page styles (UnQbdWeb2) -- Book-detail "Details tab" cards.
   These classes render inside .book-view-page, where book-reader.css defines
   the --bvr-* token layer that cascades in (light + dark). We consume those
   tokens with literal fallbacks; dark mode is handled by the token layer
   re-pointing, so explicit body.dark-mode rules below exist only where a
   hardcoded (non-tokenized) value needs a dark counterpart. */
