+test: Disable Prettier snapshot formatting
+
+Jest is not yet compatible with Prettier 3, causing snapshot updates to fail with the following error:
+
+```typescript
+TypeError: prettier.resolveConfig.sync is not a function
+    at runPrettier (node_modules/jest-snapshot/build/InlineSnapshots.js:308:30)
+```
+
+We have disabled Prettier snapshot formatting in our Jest preset as a temporary workaround. If you do not use the preset, you can manually modify your `jest.config.ts` like so:
+
+```diff
+export default {
++ prettierPath: null,
+}
+```
+
+You may have to run `skuba format` manually after updating snapshots until [jestjs/jest#14305](https://github.com/jestjs/jest/issues/14305) is resolved.
