/* The Library (crosstela.com/library): reference tables and small tools, built by site/tools/build_library.py.
   Sits on handbook.css (bilingual halves, top bar, prose, tables, way-on) and reads only site.css tokens, so both
   styles work. Swatch colours arrive as --c through CSSOM (library-pages.js); the CSP allows no inline styles. */
