Detailed Description

The one exception the fluid fallback ladder catches.

Split out of fluid_moments.h on 2026-08-28 so that solver_fluid.h can raise it too. fluid_moments.h includes solver_fluid.h, so the definition could not stay there and be visible in the window loop: the conservation guard raises it from inside the integration, where a divergence is first detectable, and fluid_runner.h catches it in exactly the same place as before.
