Notes on Implementation

Contact Form: The form includes four fields - name, email, organization, and message. Only organization is optional. The form has proper validation attributes and is setup for JavaScript validation and submission handling.
Success Message: A hidden success message element is included, which will be shown after successful form submission.
Footer Structure: The footer uses a three-column grid layout with:

Logo, tagline, and social media links in the first column
Quick navigation links in the second column
Contact information in the third column


Semantic Elements: Proper semantic HTML5 elements are used throughout, with appropriate heading levels and ARIA attributes where needed.
Accessibility: Links include descriptive text, form fields have proper labels, and social media icons have aria-labels.
Animation Hook: A highlight-row element is included for integration with the animation system.
Contact Information: Email and phone links are properly formatted with mailto: and tel: protocols for better mobile usability.
Copyright Notice: A standard copyright notice is included at the bottom of the footer.
