   A complete, clickable index of every category and title, living
   inside the pink ".writers" section. Each category is its own
   palette-coloured card (black stroke, slightly rounded) so the
   black text stays easy to scan. Shares design tokens from
   styles.css; built by Assets/js/library.js from window.LIBRARY.
