/*
 * The "Teaching a live class" guide (/blog/teach-your-bible-class-on-every-screen-at-once).
 *
 * This article keeps its own design (the Live Classroom guide artifact) instead of the
 * house article template, so it carries this stylesheet ON TOP of blog-article.css, which
 * it still links for the shared buttons and the end CTA. Every rule is scoped under
 * `.lcg` (or the `body.lcg-page` tokens), so the public nav, the footer and the shared
 * blog styles are untouched. blog-article.css zeroes margin and padding on everything and
 * strips link underlines; the rules below set what this page needs back explicitly.
