Detailed Description

Runtime multi-species composition: one coupled system, block by block.

Each block is a species (one state U) described by a ModelSpec (composition of generic bricks: transport + source + elliptic right-hand side), with its spatial scheme (limiter + Riemann flux), its time treatment and its substeps. All blocks share a Poisson whose right-hand side is the sum of the per-block elliptic_rhs; the source S acts per block. The core names no scenario; scenarios are compositions defined on the application side (adc_cases).

Python composes (brick objects); the per-cell computation (assemble_rhs<L,F>, Newton of the implicit source, multigrid/FFT) stays C++-compiled and is frozen when the block is added. No Python callback in the hot path, except a time integrator written in Python via eval_rhs / get_state / set_state.
