The single-column dialog missed the design's interaction model (figma
813-23126/813-23278, sibling frames of the linked node): selection is
not navigation. The browser now opens as one wide level; selecting a
row keeps it marked (pill + open-folder accent) and previews its
children in a second 256px column across a hairline divider, a
right-column pick advances one level, and the breadcrumb follows the
selection. New folder becomes the design's nested create dialog
("New folder in ...", Untitled-folder placeholder, Cancel/Create),
creating inside the selection and landing with the new folder selected.
Open adopts the selection, falling back to the listed level, so the
e2e path-edit flow is unchanged. The card is the design's fixed
600x420 with per-column scrolling.
