Title

Note

The title is the line above this description box and is automatically "suggested" based on your branch name.

The title should be an imperative statement summarizing its effect on the user. (As a statement, it should have a capitalized first word and no trailing punctuation.) These titles are copied directly into the release notes.

Examples:

• Implement the FooBar model
• Handle errors in track initialization
• Fix sampling of low-energy Celeritons
• Refactor code in preparation for new tracker type
• Add CI support for multiple Geant4 versions

Please do not add textual or emoji tags, such as 'CI:' or '🐛', to the title.
