How to Clean Up a Child Theme if Best Practices weren't Followed

Review Dependencies:
Use the Design Tools context menu to check dependencies and revision history.
Identify and document any custom changes made to files.
Remove Unnecessary Files:
Delete overwritten CSS and JS files if no longer needed; the original files will be referenced instead.
Handle Modules and Templates Carefully:
If modules or templates have live dependencies, do not delete them; instead, merge customizations with the updated parent theme code to maintain compatibility.
