Three books from this estate: the book-writing pack

Something a little bit different: not a build round but a writing round. Three books from this repo and the work so far, each in its own fresh session, read on tomorrow's long flight — the universe/atlas volume for 'Fractal Semantic Graphs: Meaning Through Connectivity', the book itself (title locked, full editorial freedom elsewhere), and 'Creating a Book Using Fractal Semantic Graphs' for other authors: the story of book 2's experimentations, PoCs with screenshots of the evolution, and the agentic workflow — an expansion of the v0.4 retrospective. Delivered as one dev-pack-style pack with three entry prompts, since most of the briefing is shared.
