Docker Hub blocks Iran (403) on the BUILD base images too (golang/alpine/busybox/
node) once they fall out of cache. Prefix every Docker Hub FROM/COPY --from with
mirror.soroushasadi.com/ (MCR dotnet images are reachable, left as-is). Go builders
also set GOPROXY=mirror.kargadan.ir/repository/go-group/ + GOSUMDB=off so any module/
toolchain fetch avoids the geo-blocked proxy.golang.org.
