  The whole workspace — crate::pages::admin::table_definition::ui::WorkspaceFragment,
  and what table_definition.html embeds on first load.

  Which panels appear follows how much has been selected: the copy and invoice
  template panels need a profile, everything else needs a table, and a
  backend-managed ("system") table gets none of the write panels at all,
  because the server refuses every one of them for it.
