Curated YouTube videos and locally hosted videos selected by the site maintainer.
Site maintainers can add MP4 / WebM files to assets/videos/ and register them in assets/videos/manifest.json. YouTube items can be registered with a video ID. For embedded playback, deploy the site over HTTPS (for example Cloudflare Pages); file:// previews may not send the HTTP referrer required by YouTube and can trigger error 153. A direct YouTube fallback is provided for each video.
