Populated from the arc42-template (EN/adoc) with project-specific content
across all 12 sections:
1. Introduction and Goals — requirements overview, quality goals, stakeholders
2. Architecture Constraints — technical (engine, collision, coordinates),
organisational (squash-merge, visual review, provenance), conventions

7. Deployment View — dev workstation and packaged build infrastructure
8. Cross-cutting Concepts — coordinate system, collision model, lighting,
materials, data provenance, QA harness
9. Architecture Decisions — 7 ADRs (dynamic lighting, UE materials,
C++ collision helper, grounded reset, core ticker, Y convention,
headless Blender)
10. Quality Requirements — overview table + 7 measurable scenarios
