- Updated page-91.php to add an ID to the c-tabs div for better targeting.
- Changed package name in content-page.php from 'brpfinanse' to 'BRPP_prawo_podatki' and updated related function calls.
- Cleaned up content.php by removing commented-out code and unnecessary whitespace.
- Added VSCode settings for live Sass compilation.
- Created a new page template (page-3.php) for the privacy policy with appropriate structure and comments.
