📝 Walkthrough

Walkthrough

Point-cloud routes now use collection-grid behavior without rendering the filter panel. A workspace test verifies that the filter panel is absent on point-cloud routes.

It renders the filter panel and show-filters button only for other grid types. The workspace test verifies that filter-panel-body is not rendered for point-cloud routes.
