Introduce TankDefinition/TankCatalog loaded from Tanks.json, bundle the Drachengas USDZ tank models, add tank selection and preview views, and update the AR experience, editor and project views to use the catalog. Includes tests for catalog loading and model selection. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
