I reviewed the PR title/description, linked issue #4441, checks, and the diff before labeling.

Labels applied:

• level:beginner: the change is a single 94-line theme-contrast test file in app/api/track-user/route.theme-contrast.test.ts, and the assertions are straightforward theme and contrast checks.
• quality:clean: the helper calculations are isolated inside the test file, and the scenarios are compact and readable.
• type:testing: the PR is dedicated test coverage for the track-user route.
• type:design: the suite is specifically about dark/light visual cohesion and contrast behavior.

I’m leaving this as a neutral comment rather than approving because the repo checks are green but the PR is still carrying a failing Vercel status context. That looks like a deployment integration/auth issue rather than a code failure.

To unblock it, the Vercel GitHub integration for the repo/team needs to be re-authorized or the status needs to be marked non-blocking by maintainers. Once the Vercel context is green, this can be reviewed normally.

[Aamod007]

The coverage in �pp/api/track-user/route.theme-contrast.test.ts stays simple and targeted. It checks the dark/light contrast expectations, header shape, and the success payload without drifting away from the route contract.
