Instruction: Create the main stylesheet for the website.

This CSS file defines the visual identity of the site, aiming for a rich, trustworthy, and modern design. It includes:
- A professional color palette with a deep blue primary color and complementary grays.
- Typography using 'Merriweather' for headings and 'Lato' for body text to create a classic, readable feel.
- A responsive layout using Flexbox and media queries to ensure the site looks great on all devices.
- Styling for all major components, including the header, hero section, service cards, forms, and footer.
- Subtle hover effects and transitions to enhance user interaction.
- Custom styling for the AOS animations to ensure they are smooth and visually appealing.
