An asciidoctor extension providing a uri:: block macro that resolves a Spotify or YouTube URI live at build time (via oEmbed, no caching) and renders a branded card carrying the resolved title, artist or channel, a thumbnail, and a plain link out. Cards participate in the document's cross-reference and counter system. A companion uri: inline macro cites a track/video in running prose, optionally as a live Spotify Code (code=true); layout=album renders a vertical Spotify card built around one. Third-party providers register without modifying this gem.
