The Brain as cells: every atom fuses a Wikidata concept, the Lean declaration that formalizes it, its entries in nLab / LMFDB / Stacks / MathWorld / …, its WikiLean article and its arXiv statements into ONE object. Atoms nest inside the Mathlib folders that hold their code, and the lines between them are synapses — every weak bond between two atoms, collapsed into one edge that keeps every trace. Click anything.
