 The GitHub repository, branch, and content directory are inferred from the local git checkout and `VERCEL_GIT_*` variables. Override them at runtime with `NUXT_DOCS_*` variables: `NUXT_DOCS_GITHUB_OWNER`, `NUXT_DOCS_GITHUB_REPO`, `NUXT_DOCS_GITHUB_BRANCH`, and `NUXT_DOCS_CONTENT_DIR`.

 | `VERCEL_BYPASS_TOKEN` | Lets the revalidation endpoint purge ISR pages. Must be available at **build** time — it's baked into the deployment's ISR configuration, so a runtime-only value leaves purging broken. |

 `VERCEL_AUTOMATION_BYPASS_SECRET` is set automatically when [Deployment Protection](https://vercel.com/docs/deployment-protection) is enabled; it lets the revalidation endpoint call back through the protection wall.
