Tested multimedia embedding in Amytis today. Since rehype-raw is enabled, standard HTML <iframe>, <video>, and <audio> tags work directly inside Markdown — no plugins needed.

A few patterns that work well:

• YouTube / Vimeo — wrap in a padding-bottom: 56.25% container for responsive 16:9
• Spotify / Apple Podcasts — fixed height iframes (152px for compact, 352px for full player)
• HTML5 <video> — fully native, supports poster, loop, autoplay muted
• HTML5 <audio> — great for podcast episodes or background music samples
• Twitch — needs the parent query param set to your domain

The loading="lazy" attribute is underused — always worth adding to below-the-fold embeds to keep the initial page fast.
