The .ts source gained the unbounded width/height guard when TileLayer went optional-dimensions, but the committed generated twin was never re-synced. Surfaced by running examples:sync for the new infinite-terrain example.
…g, procedural providers
…self-heal A texture passed while unhydrated gets its Spritesheet-sliced frames reset to the full atlas by the Sprite texture-load self-heal once it hydrates. Await the load like the tileset texture already does.

loader.get()get their sliced frames reset to the full atlas by the Sprite texture-load self-heal (affects ~5 merged examples; root cause analysis in the branch review). This PR's two new examples avoid it by awaiting the texture.scripts/sync-example-capabilities.tslistswebWorkersin its ordering array but has no derivation rule for it.
