 ### Added
 - **Language switcher for multilingual site support** (#374) — a globe icon dropdown in the bottom toolbar that enables users to switch between translated versions of a lecture site. Only renders when 2+ languages are configured via `html_theme_options`. Includes keyboard navigation, click-outside-to-close, and dark mode support.
 - **SEO hreflang tags** (#374) — automatically injects `<link rel="alternate" hreflang="...">` meta tags in `<head>` for all configured languages, improving search engine discovery of translated content.
