Contributor guide
Research direction
Search the thumbnail creation path and inspect how CanvasRenderingContext2D currently scales images. Compare the imageSmoothingQuality API with pica@6.1.1 and review the linked Element issue for expected quality and browser constraints. Done means thumbnails use an agreed higher-quality scaling approach without breaking supported browsers, with relevant tests or visual verification.
