Discovered how Hatch (Python's recommended build backend) determines which files to include: https://hatch.pypa.io/latest/plugins/builder/wheel/#default-file-selection. For my purposes, the relevant idea is that it'll include all files in the src//init.py folder, but the init.py file must be present.

These can be overriden using the [tool.hatch.build.targets.wheel] table.
