summary

Live demo of a small site that swaps images and streams based on viewport and bandwidth, with concrete numbers: using picture element and srcset cuts delivered image bytes by about 60% and shaves ~1s off LCP in tests, adding lazy-loading and an image CDN drops requests and bandwidth further. Shows exact markup, a webpack image pipeline, and a working adaptive-stream example so the build and performance claims are verified rather than just promised.
