Could you build this?
Partial While the interactive drag-and-drop web UI is straightforward to build, writing an exact deterministic algorithm to infer hierarchical flexbox layouts from arbitrary 2D bounding boxes without AI requires non-trivial computational geometry and tree-partitioning heuristics.
What it would actually take: A production version requires a client-side JavaScript engine implementing spatial clustering and recursive 1D/2D space partitioning (e.g., recursive bounding box slicing or XY-cut algorithms) to derive row/column flex containers. Edge cases like overlapping elements, wrapping, and alignment ambiguities require custom heuristic scoring. Building this requires solid background in computational geometry and CSS layout specification internals rather than generic CRUD.
