// x2t WASM, extensionless indexed fonts, the embed save round-trip...).

// The image must exist as `document:e2e` before the run -- use
// `pnpm run test:e2e:docker`, which builds it first, or build manually with
// `pnpm run docker:build`.

// the vite preview server, which serves different headers.
