 * Quotewise Library — reading treatment for Wagtail content pages
 * (/about/ hub + spokes, /library/ index + articles).
 *
 * In family with the app (beige ground, saddle brown, tan borders,
 * white cards) but distinct: serif reading voice, paper-sheet article
 * surface, persistent section ribbon. Replaces about.css + content.css.
 *
 * The site is light-only (color-scheme: light in base.html).
