- Created `admin-head.php` for consistent <head> markup across admin pages. - Created `admin-nav.php` for shared navigation bar, reducing duplication. - Updated all admin pages (account, hours, index, login, menu, users) to utilize the new components. - Added security headers to `auth.php` and `index.php` for improved security. - Introduced `security-headers.php` to manage security headers across the application. - Moved inline styles from admin pages to SCSS files to comply with Content Security Policy (CSP). - Normalized file permissions during build process to prevent permission issues on deployment.
