/* The books pages (books.php: the shelf, the search, the categories, a work; and, with book-reader.css, the reader) in
   ZWIBook's own design (Larry, 2026-10-07: "I like the original ZWIBook design. It was very nice, and I worked a long
   time on it … resurrect it"). From ZWIBook's stylesheet.css (gitlab ks_found/zwibook): its blue header with white
   icons (assets/zwibook/, its images/icons), Arial for the interface and Times for titles, its tabs, list rows,
   category list, cards (its About page's), buttons, sort menu. Inside /books its look wins over the site's where they
   differ (DESIGN.md §6d). Dark is ZWIBook's palette darkened (ZWIBook had no dark mode); every color is a --zb- token. */

   neither (Android), and Liberation Serif, ZWIBook's reading font (fonts/ in ZWIBook). Calibri and Cambria, also in its
