    "incantation": "For a linked Vercel project, build and push its container image with `vercel vcr build <engine> <context> <repository>:<tag> --push`; the release note says repository and tag default to the project name and `latest`, and engine arguments after `--` are forwarded. `vercel vcr push` pushes an existing image; combined build and push uses zstd by default as described in the release note.",
    "examples": [
      "vercel vcr build docker . <repository>:<tag> --push",

      "Prerequisite: Have access to the target project and the chosen local container engine installed and running. The official Vercel example uses Docker.",
      "The default repository is the project name and the default tag is `latest`.",
      "`vcr build --push` uses zstd by default with Docker via Buildx and Podman/Buildah on push.",
