   Live preview of the Audio Catcher side panel.

   This is a faithful HTML/CSS recreation of the extension UI, not a
   screenshot: values are carried over from the extension's own
   css/style_append.css and css/dialogs.css. It deliberately omits the site
   shortcut rail, so no third-party brand appears on the marketing site.

   Namespaced .acp-* so nothing here collides with the page styles.
