/* Layout contract (see DIRETRIZES-DE-CONTINUIDADE.md):
   - The workspace has a fixed geometry. State changes never insert or remove
     blocks in the flow: they change text, attributes or visibility inside
     reserved boxes. Stage panels and toolsets are stacked in one grid cell.
   - Overlays on the canvas (empty state, triangulation progress, layers menu)
     are absolutely positioned and never move other elements. */
