Zenith Walls deploys a three-tier image normalization pipeline to bypass Next.js 15 edge function CPU limits when serving high-resolution assets. The wallpaper platform routes requests through a custom proxy API to handle Cloudflare R2 bucket bindings and inject headers. This architecture prevents browser lockups across a catalog of 70,000 images.
