Detailed Description

flow — device property closures: material properties / body forces as functions of fields.

A closure writes one target cell field (a material property like rho/mu, or a momentum body-force component) as a pointwise function of one or two input fields (a transported scalar, pressure, a phase fraction). Dispatch is a host-side enum switch launching ONE dedicated Kokkos kernel per closure kind — no per-cell Python, no device virtual dispatch. The Solver applies its closure list in registration order at the top of step() (properties frozen over the step; segregated coupling).

This is the seam for field–field coupling: Boussinesq buoyancy (force from temperature), temperature-dependent viscosity (Arrhenius), composition-dependent density (linear mixture), and tabulated properties. A user escape hatch (set_field on a property) bypasses closures entirely.
