Shadow DOM is a web component feature that lets you attach an isolated DOM subtree to any HTML element, hidden from the main document’s standard queries. A querySelector('audio') on the main document cannot see inside a Shadow Root unless you specifically traverse into it. If fermaw’s player was mounted inside a Shadow Root, basic DOM searches would come up empty.

Moving the orchestration layer and using the correct regional endpoints cut e2e latency in half. Service placement makes a huge difference.
