I'll implement all these changes to increase margins and update the header controls.

I've implemented all the requested changes:

1. Increased Margins

• Significantly increased the left and right margins by updating the padding classes:

  • Changed px-8 md:px-16 to px-16 md:px-32 for both the header and main content
  • This provides much more whitespace on both sides of the content

2. Added Light/Dark Mode Toggle

• Added a theme toggle button in the top right corner
• Used the Moon/Sun icons from Lucide React to indicate the current theme
• Implemented proper theme switching using the useTheme hook from next-themes
• Added dark mode styling throughout the entire page

3. Replaced "Book a Call" with Language Toggle

• Removed the "Book a Call" button from the header
• Added a language toggle (EN/ES) that allows switching between English and Spanish
• Implemented a smooth animation when switching languages
• Restored the full content for both languages

4. Added Dark Mode Support

• Added dark mode classes throughout the components
• Updated the ToolkitItem and NavigationBar components to support dark mode
• Ensured proper contrast in dark mode for all text and UI elements

The site now has:

• Much wider margins for a more spacious layout
• A theme toggle for light/dark mode
• A language toggle for English/Spanish
• Responsive design that works on all screen sizes

I'll update the theme toggle to automatically set dark mode by default.

I've updated the code to automatically set the theme to dark mode when the page loads. Here's what the changes do:

1. Added a new useEffect hook that runs when the component mounts and sets the theme to "dark" by default
2. Kept the toggle functionality of the button so users can still switch between light and dark modes
3. The theme will now start in dark mode automatically on every page load

This ensures that users will always see the dark theme first, but still have the option to switch to light mode if they prefer. The Sun icon will be displayed initially (indicating they can switch to light mode), and if they click it, the theme will change to light mode and the button will show the Moon icon.
