Notes

Each layout stores complete flex properties: direction, wrap, align, justify, gap, and per-item grow/shrink/order
The export command generates clean, production-ready CSS with class names derived from layout names
Use row and column shortcuts for common patterns instead of create
Item properties (grow, shrink, order) are stored per item index within each layout
