/*
 * Library article pages: learn guides, blog posts, product docs (/docs), and developer docs (/developers,
 * /learn/answer-api). Loaded last by every library page (scripts/seo-shared.mjs libraryStylesheets), with class
 * names of its own (lib-*, prose, doc-*), so these pages don't inherit the older landing, tools, and blog rules.
 * Same look as the homepage: Geist, paper background, black ink, violet only for links, mono labels.
 * The closing call to action and the footer are the shared SiteCta and SiteFooter (site-chrome.css).
