OINK 1.3.2 removes the mandatory Dart Sass installation introduced in 1.3.1.
Ordinary site builds and previews use **Hugo Extended and its built-in LibSass**.
Main styles, ReDoc styles, dark syntax highlighting, and project SCSS hooks
remain supported. All independent readability and FileTree fixes from 1.3.1
remain included.

## Build requirements {#build-requirements}

**Hugo Extended 0.166.0** is the minimum and default development and strict CI
version. Go is needed to resolve Hugo Modules; no external Sass executable,
Node.js, or npm is required for ordinary site builds.

**Hugo Extended 0.168.0** can also build and preview the site. It reports an
upstream LibSass deprecation warning. This warning is accepted and remains
visible. If you use `--panicOnWarning`, it will fail the build; use 0.166.0 for
the strict publication gate. OINK does not suppress other warnings.

The default Hugo version stays pinned. Future upgrades must preserve the
consumer dependency boundary. A Hugo release that removes built-in LibSass
requires a separate compatibility decision.

## Upgrade {#upgrade}

Update the module pin:

```sh
hugo mod get github.com/pgsty/oink@v1.3.2
```

Commit the updated `go.mod` and `go.sum`. Remove Sass installation steps that
were added solely for OINK 1.3.1, and set the default Hugo workflow version to
`0.166.0`. Sites using a vendored theme must refresh that copy as well.

Existing content, appearance settings, and project SCSS customizations need no
migration. See the [toolchain contract](/docs/design/architecture/#hugo-toolchain).

## Validation {#validation}

The theme's focused compiler check builds real main and ReDoc styles with no
Sass executable on `PATH`. It checks project-variable and project-style hooks
and the dark Chroma palette. Hugo 0.166.0 uses strict warnings; the separate
0.168.0 case accepts only the known upstream LibSass warning.
