The help system was already fully implemented with:
- 74 help articles across 8 categories (Basics, Features, Setup, Advanced, Interface, Troubleshooting, Maintenance, Integration)
- Fuzzy search functionality matching the command palette
- Keyboard shortcut (Ctrl+?) to open help overlay
- Category filtering and action links to relevant dashboard sections
This commit fixes the addHelpButton() function to work with the existing
HTML button (id="help-btn") instead of trying to add a duplicate button.
Also removes duplicate CSS since styles are already in index.html.
