architecture

• One question per diagram: who uses it, how the repo is built, what it relies on. There is no app and no server, so the diagrams draw what the repo is.
• The diagrams are generated: edit the .json in architecture/, then run archify finalize architecture <name>.json <name>.html --quality showcase there. Never hand-edit the .html.
• Architecture is canon's, not the design set's: the designs are what Babul draws, and nothing else.
• Where the site will be served from is open, task T002.
