## Keyboard meshes

- **No third-party GLB shipped.** Sketchfab “IBM Model M Keyboard” by timblewee (CC-BY 4.0, commercial OK with credit) and Poly Pizza / Kenney keyboard (CC0) were researched; downloads required login or were blocked by bot protection from this environment.
- **Shipped:** stylized procedural boards in `keyboards.js` (Technology 83 / KeyFeel). Flagged in UI Assumptions — not photoreal OEM geometry.
