Submodule functions in __all__ get correctly hoisted to top-level docs, but not submodule variables

Problem Description

I have a package with lots of modules within. In the package __init__.py, I define __all__ with all of the functions I want to expose to the user. This works great, and pdoc puts all the functions in a single list under "API Documentation". Exactly what I want.

The problem is that I also include a single settings dictionary variable imported from a submodule, alongside all the functions imported from submodules. I include that in __all__, but for some reason pdoc then creates a separate "Submodules" section of the documentation that lists "settings" underneath, that links to a separate page, that documents the variable.

I absolutely want to include the variable documentation -- I just want it to be listed next to the functions in the order it is specified in __all__. I don't see any reason for forcing variables that aren't functions into submodule listings, so this seems to be a bug?

Expected behavior: non-function variables in __all__ get included alongside function variables
Actual behavior: non-function variables in __all__ are still being documented as belonging to submodules

System Information

pdoc: 15.0.1
Python: 3.12.8
Platform: macOS-15.2-arm64-arm-64bit

Reproduce the behavior with a package init.py that imports functions and a settings dictionary from submodules and lists them in all. Start by tracing how pdoc classifies imported functions versus variables; done means the variable appears with the functions in API Documentation, in all order, while remaining documented.
