Do galaxy-galaxy lensing and clustering in transverse physical separation r_p (Mpc/h) rather than angular theta where spectroscopic z is available: cleanly isolates scale ranges and gets the BNT scale-cleaning benefit for free. Cosmic shear stays angular. Delta-Sigma in physical units; number of radial bins (6-7) TBD. Ties into the UNIONS-WL/Smokescreen fork PRs (blinding, modelling arbitrary data vectors).
