Fast-forward the deployment checkout to the exact healthy image commit while refusing tracked changes, divergence, or an unexpected branch. Ignore release metadata stored beside the checkout.
Build and test the Next.js application once with persistent BuildKit caches, smoke-test the immutable runtime image, and activate that same image through the shared production Docker daemon with serialized rollback-safe deployment.
Replace the blocking asset loader with progressive rendering, defer expensive media and Three.js work, and reduce hydration and animation costs. Move deployment from a static Nginx export to the standalone Next.js runtime with optimized dynamic images.
