✓ Zero Main-Thread Impact — Shopify Web Pixel
LittleData runs as a Shopify Web Pixel — an isolated background worker managed natively by Shopify. It cannot block your page rendering, delay interactions, or affect your Core Web Vitals.
Web Pixels run outside the main browser thread in Shopify's sandboxed environment. CPU benchmarking of the main thread doesn't apply here — this is a structural guarantee, not a measurement result.
