/*
 * style-blog-article-light.css — TriDigi Blog ARTICLE PAGE, light editorial theme
 * ─────────────────────────────────────────────────────────────────────────────
 * Linked ONLY by individual article pages (e.g. the zero-click-searches post),
 * AFTER style.css and style-blog.css, so it wins the cascade on shared
 * selectors without needing !important.
 *
 * Scope discipline:
 *   - blog.html (the archive/listing page) also carries body.blog-page and
 *     must stay on the existing dark theme — so every rule here that touches
 *     a selector shared with blog.html (nav, WhatsApp float, footer helpers)
 *     is scoped under body.article-light, a class added ONLY to article
 *     pages using this stylesheet.
 *   - .art-* / .toc-list / .sidebar-* / .related-item selectors are, today,
 *     only ever rendered inside .art-layout on an article page, so they are
 *     redesigned directly without the extra prefix.
 *
 * Contents:
 *   1. Nav + WhatsApp float (light overrides, scoped to .article-light)
 *   2. Article hero
 *   3. Layout + sidebar (TOC, share, related)
 *   4. Article content typography (headings, body, lists, emphasis)
 *   5. Lead paragraph
 *   6. Key insight callouts
 *   7. Stat blocks
 *   8. Comparison table
 *   9. Numbered strategy blocks
 *   10. GEO featured section
 *   11. FAQ accordion
 *   12. CTA strip
 *   13. Light footer
 *   14. Responsive
