THREE.JS / FOUNDATIONS 344
Break the strip.
One indexed line contains two polylines. The fixed restart index must split them without drawing the forbidden bridge across the center gap.
Initializing primitive-restart probe—
Preparing one indexed line-strip and its fixed restart sentinel.
The line-strip is waiting for its first indexed draw.

The WebGPU path promotes a non-normalized Uint16 index buffer and rewrites 0xffff to the fixed 0xffffffff restart value. The WebGL2 comparison keeps the native Uint16 sentinel.
Primitive restart is unavailable.The requested backend could not initialize this study.
Primitive-restart initialization failed.
The renderer could not initialize.
This route studies indexed line-strip topology and typed-index adaptation; interleaved indices remain source-only because the indexed contract accepts a BufferAttribute, not an interleaved attribute.
