Description
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).
Context: Paris meeting notes

Research direction
Start with the Paris meeting notes and the UNIONS-WL/Smokescreen fork PRs referenced in the issue, then locate the clustering, galaxy-galaxy lensing, and cosmic-shear entry points. Done means the separation choices and Delta-Sigma units are implemented consistently, with the radial-bin decision resolved and the fork integration accounted for.
