With the newly supported fuzzy matching in our test-web runner, we can now define the expected maximum color channel and pixel count errors per failing test and set a baseline they should not exceed. The figures I added to these tests all come from my macOS M4 machine. Most discrepancies seem to come from color calculations being slightly off.
