What this first release supports
Pedestrian rectangles, L-shapes, contained rectangular exclusions, single-size grids or exact set coverage, simple borders, user-specified base and bedding, joint packages, selected edge restraint, spikes, and rectangular fabric lanes.
Adjustments remain separate
Geometric cut excess, broken-unit reserve, layer order factor, package surplus, and pallet surplus are presented as different quantities rather than one ambiguous waste number.
Important limits
Complex borders use an explicitly additive measured purchase count; their installed footprint is not inferred. Fabric lanes require one simple rectangle. Permeable pavers are materials only; reservoir, underdrain, infiltration, storage, and overflow design are outside this calculator.
