/*
 * Blog detail page common styles (zh-Hans).
 *
 * This stylesheet is the SINGLE source of truth for blog-detail-page UI:
 *   - Page two-column layout (.article-page-wrap / .article-main / .article-sidebar)
 *   - Breadcrumb (.breadcrumb) injected by article-recommend.js
 *   - Article header (.article-header) injected by article-recommend.js
 *   - Long-form body typography (.article-body h2/h3/p/ul/ol/blockquote/table/code)
 *   - Callout boxes (.callout / .callout-tip / .callout-warn / .callout-info)
 *   - In-article CTA card (.inline-cta)
 *   - Sidebar TOC (.toc-card / .toc-list)
 *   - Bottom product recommendation (.product-recommend) injected by article-recommend.js
 *   - Prev/next pager (.post-pager) injected by article-recommend.js
 *     (per § Blog Detail Page Spec §11)
 *   - Related-posts grid (.related-posts) injected by article-recommend.js,
 *     simultaneously fulfills the role of "Further Reading" + "Related Articles"
 *     (per § Blog Detail Page Spec §11; the legacy hand-authored .related-reads
 *     block has been removed — the auto-injected one is its replacement)
 *   - Floating download widget (.float-widget) injected by article-recommend.js
 *   - Responsive breakpoints
 *
 * Per history_old.md § Blog Detail Shared Component Extraction, blog article HTML files MUST
 * NOT re-declare any of these rules inline. The visual contract for every
 * blog detail page lives here and here only.

 * Related posts grid (.related-posts)
 *
 * Injected by article-recommend.js IMMEDIATELY AFTER .post-pager. Multi-
 * purpose panel: simultaneously fulfills the role of the legacy hand-
 * authored "Further Reading" block (now removed) AND the auto "Related Articles" grid —
 * one panel, one visual style, two responsibilities. Per § Blog Detail Page Spec
 * §11 cards MUST carry: category, full title, summary, action hint, and
 * the whole card MUST be a real <a href> so crawlers can follow.
 *
 * Visual style intentionally mirrors what used to be .related-reads:
 * light green-indigo gradient panel, brand-green eyebrow, soft card
 * grid — distinctly LIGHTER than .product-recommend (the dark product
 * CTA above it) so readers immediately see "this is more reading" vs
 * "this is the product CTA".
