Detailed Description

Number<T> reports GetNDim = 0 (no NDim member, no getNDim()), causing all spatial derivatives to return ZeroType at the free-function level.

It satisfies HasEvalMethod (works in binary expressions) and IsScalarType (no complex/SU2/matrix getters), so Number<T> * Field dispatches correctly.

The 4-way operator+= dispatch handles: * Lattice expressions (NDim > 0): spatially average, then add * 0-dim expressions (another Number, scalar*Number): eval directly * Arithmetic (plain double/float): add directly * ZeroType: no-op

Unit test: ctest -R test-number

@vocab-summary A runtime-mutable scalar that takes part in expressions: change its value and every expression holding it sees the new one, without rebuilding the tree.
