putImageData() ignores canvas transforms, so on displays with devicePixelRatio > 1 (Mac Retina, etc.) the tile globe rendered at 1/DPR size in the top-left corner while distance rings and spots drew correctly. Fix: paint tile ImageData onto a temporary canvas, then use drawImage() which respects the active DPR transform. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
