Review found in-call tiles use MediaView->Avatar, not TileAvatar, so the decoration never rendered in-call (CRITICAL). Move the overlay into MediaView, gated on the avatar's own visibility (!(video && videoEnabled)) so it never floats over live video; revert the TileAvatar changes. Also ref-count the io.lotus.decorations registration (one shared handler, no double-reply) and stop clearing the map on teardown so a transient remount doesn't drop decorations (HIGH/MED).
