WHY THIS IS DIFFERENT
A build-oriented diffuser tool, not only a residue sequence.
The studio computes the QRD prime-order residue sequence, converts it into real cut depths, flags max-depth clipping, estimates useful range from depth and well width, and exports a buildable SVG plus cut-list CSV. It is designed for rear-wall or side/rear diffusion decisions after RT60 and bass behavior are already under control.
Boundary: Build planning only. It does not replace polar scattering simulation, safety review, or workshop judgement.
