[BUG] Add consistency in variable naming

[iMartzen]

#Describe the bug

This codebase mixes python's standard snake_case style with camelCase and lowercase styles.
It's not uncommon to preserve the casing of variables from an external API:

productArea = pO['productArea']

but for variables like pageNum that are only being used in python, it's best to stick to camel_case like page_num. This will make reading and searching the code easier for python engineers.

🔹 Style Consistency (Nice to have)
