[pamelafox]

This PR is currently failing CI:
#299

Create a new PR that accomplishes the same goal as that PR, but passes CI.

Here's a summary of why that PR is failing:
The failure is due to a dependency conflict between package-a and package-b. The workflow attempts to upgrade package-b to version 2.0.0 while the installed package-a is locked at version 1.5.0, which is incompatible with any package-b version higher than 1.8.0. This conflict causes the dependency resolution step to fail, preventing the workflow from continuing.

Relevant logs:
ERROR: Cannot resolve dependencies for package-a==1.5.0 and package-b==2.0.0
Conflicting dependencies: package-b 2.0.0 requires package-a <2.0,>=1.8, but found package-a 1.5.0.

Verification tips

If you need to create a virtual environment, use the .venv folder, like:

python -m venv .venv

When you have updated packages, make sure you can install them successfully in the virtual environment.
To decide what command to use to install the packages, check the repo's README.md and GitHub Actions workflows in the .github/workflows directory.

Leave a comment on the PR indicating what command you used to verify successful installation.
