Description
Sometimes only one or two images need an increased tolerance, but we can only increase tolerance on the entire test set.
I'm not sure how best to indicate it. Maybe by using a marker on one of the parameters.

Research direction
Start by tracing how parametrized tests currently apply tolerance across an entire test set. Review the existing tolerance configuration and image-comparison entry points, then determine how a parameter marker could identify selected images. Done means individual parameters can request increased tolerance without changing the tolerance for the rest of the set.
