Lint for how it looks.

Tastelint reads the screenshots on a pull request.

How it works

1. Open a ready pull request with screenshots of the changed UI.
2. When the build is green, Tastelint reviews those pictures once.
3. A review lands: what looks off, why, and what to change. Comment /tastelint to run it again.

Comment /supertastelint to run all ten review levels in sequence.

Or call the API whenever — locally, before a pull request, without attaching screenshots.
