…lats accessor - New GSplat LOD streaming test example (gaussian-splatting category) with thumbnails. - Engine: GSplatOctreeResource.numSplats accessor returning the full-detail (LOD 0) splat count of a streamed gsplat resource (the LOD system keeps only a view/budget-dependent subset resident at runtime). - Examples: PREFERRED_DEVICE config flag (@Flag PREFERRED_DEVICE=webgpu|webgl2) to set the first-time default graphics device when the user has no stored preference; an explicit user choice always wins. Wired through iframe/state.mjs, utils/example-source.mjs, validated in eslint.config.mjs, documented in README.md. - .gitignore: ignore .claude/.

Adds a new Gaussian Splat LOD-streaming test example, plus the small framework and engine additions it relies on.
Changes:
GSplatOctreeResource.numSplats: read-only accessor returning the full-detail (LOD 0) splat count of a streamed gsplat resource. The LOD streaming system only keeps a view-distance / budget-dependent subset resident at runtime; this reports the total.PREFERRED_DEVICEconfig flag: new// @flag PREFERRED_DEVICE=webgpu|webgl2that sets the first-time default graphics device when the user has no stored preference. An explicit user choice (localStorage / URL) always wins; defaults towebgl2when unset. Wired throughiframe/state.mjs(device resolution order),utils/example-source.mjs(config typedef + parsing), validated ineslint.config.mjs, and documented inREADME.md..claude/.API Changes:
GSplatOctreeResource.numSplats(getter).
