  POST /admin/tables/builder — crate::pages::add_table::ui::BuilderFragment.

  The whole builder, which is also what `add_table.html` embeds on first load.
  Every control posts the entire draft back to /admin/tables/builder and swaps
  this markup in again, so the rules live on the server exactly as they do in
  the TUI client. The hidden inputs in the columns, relations and display
  sections are what carry the draft across requests.

{#
  A failure is a dialog, not an inline alert: the builder is taller than the
  viewport, so an alert at the top is off screen for anyone who has scrolled
  down to the column list or the Create table button. The alert stays too, as
  what is left on the page after the dialog is dismissed.
