Documents the content-author contract for catalog item GLBs: slot_ material naming + deriveSlotId rules, authored defaults and pascal_material extras, the cutout reserved mesh, the ~1 UV unit/m world scale, vertex colours for fixed detail, and the validated Blender + glTF export recipe (Custom Properties export gotcha, gltfpack -ke extras preservation). Indexes the page in the architecture README and links it from materials-and-themes.md (previously a dangling "phase-6 Blender recipe" reference).

Architecture
Canonical rules for code that touches packages/core, packages/viewer, packages/editor, packages/mcp, or apps/editor. Read on demand from AGENTS.md and from .agents/skills/review-architecture/SKILL.md.
