  # NB: we deliberately do NOT broadcast a refresh here. Layout PATCHes
  # come from the user dragging/resizing in their own browser — the local
  # gridstack already reflects the new geometry. Broadcasting back would
  # morph the same DOM mid-interaction, which destroys gridstack's resize
  # handle bindings on every other tile and locks subsequent resizes.
  # Other viewers pick up layout on next navigation; panel CRUD still
  # broadcasts via Panel#broadcasts_to.
