Detailed Description

Phase A4 — per-(LID unit, layer, species) transported state.

Plan §7 A4 asks for a "generic per-layer species block — heat reuses it", so this carries a species stride from the start. Water age is species 0; H5's temperature becomes species 1 by raising n_species and writing its own row, with no second array and no change to the layer indexing.

LID units live in per-TYPE groups (LIDManager::group(t)), not one flat list, so group_offset maps (type, unit-within-group) to the flat unit index this block is keyed on. It is built once from the manager and asserted against it on every use.
