Visual distinction: - Populated dimension: dashed cyan ring + [+] indicator - Empty dimension: subtle gray dashed ring + [○] indicator - No dimension: plain station (no ring) Context menu changes: - "Open dimension" on nodes that have children (zooms in directly) - "Add dimension" on nodes without children (creates empty zoomable space) - Removed old "Add child node" option Add dimension creates an empty children structure on the node with proper parent metadata. The node immediately shows the [○] indicator and becomes zoomable. User enters and builds tracks with FAB + branch handles. Truly recursive metro — any station can contain a world.
