/**
 * TeachDemy — Single Article page design (Round 12).
 *
 * Full redesign of the single post page, rendered by the child
 * theme's single.php template (replaces Woodmart's default blog
 * layout). Structure:
 *
 *   .td-article-page
 *     └ .td-article-hero         — navy band: crumb, category pills,
 *                                  h1, author/date/read-time meta
 *     └ .td-article-layout       — 2-col reading layout
 *         ├ .td-article-maincol  — featured image + article body
 *         │   └ .entry-content   — (§18 TOC lives here until §33 JS
 *         │                        moves it into the sticky rail)
 *         └ .td-article-side     — sticky rail: TOC slot + course CTA
 *
 * The article body keeps the .entry-content class so every existing
 * JS enhancement (TOC, scroll-spy, font-size pill, reading time,
 * heading anchors, highlight-share, resume pill, reading list,
 * copy-code) keeps working. Typography for .entry-content lives in
 * this file — engineering-grade: styled headings, blockquotes,
 * code blocks, tables, figures and callouts.
