architecture

• One question per diagram: who uses it, how the web app is built today, the planned backend, what it relies on.
• Today the web app runs on seed data in memory and the mobile app is a scaffold. The backend and the services are planned in architecture-overview and not locked (tech-stack is a draft); the diagrams say "planned" where nothing is built.
• 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.
