/* EchoDoc motion + feedback polish (visual pass 2026-09-24).
   Loaded ONLY by index.php, so offline.html (body.echodoc-standalone) never sees it.

   any other ancestor of the fixed Read Aloud bar a transform, filter, backdrop-filter or
   contain: those would make it the containing block and break position:fixed.
