+### Live only links out to playback, it doesn't embed a player
+
+NIP-53's `streaming` tag is typically an HLS (`.m3u8`) URL, which no browser plays natively
+without a library like hls.js. Rather than pull that dependency in for a first cut, the Live
+app (`src/apps/live`) shows the stream's metadata and chat and opens `streaming` (or
+`recording`, once `status` is `ended`) in a new tab. Spaces/interactive rooms (kind
+30312/30313) are a separate, larger effort — see the tracking issue.
+
 ### Web bookmarks are one event per URL, not a list
 
 Unlike a NIP-51 list, each NIP-B0 web bookmark (kind 39701) is its own addressable event —
