Detailed Description

Mesh + transport BC + aux shared by a block closures.

aux is NOT owned: it points to the System aux (lifetime longer than the block, stable address).

EMBEDDED BOUNDARY / LEVEL-SET DOMAIN (T5-PR3 effort): domain_mask and eb_domain point (NOT owned) to the 0/1 mask and the level-set domain descriptor of the System (members with STABLE address). They are used ONLY to build the optional embedded-boundary transport advances (build_block); read BY POINTER at the step, the order add_block / set_disc_domain does not matter. nullptr -> no embedded-boundary advance (stepper on advance, bit-identical). The mask is materialized / the descriptor is set by set_disc_domain (the disc is one instance of the contract, cf. numerics/embedded_boundary.hpp).
