Now let me generate the hero image and build the full site. Let me create all the components and images.

Now let me update the globals.css with a dark theme, the layout, and build all the components.

Now let me create all the section components and the main page:

Now let me assemble everything in the main page:

The site for Joaodev41 is now complete. Here's a summary of what was built:

• Dark, sophisticated theme with a navy/charcoal palette and blue accent color, using Inter + Space Grotesk fonts for a modern tech aesthetic
• 10 full sections: fixed navbar with mobile hamburger menu, hero with strong CTA, brand positioning, client pain points, solutions grid, services bento grid, technology section with a decorative code block, exclusive app bonus highlight, trust signals, and a powerful final CTA
• All CTAs redirect to WhatsApp with a pre-filled message ("Olá, quero contratar um site profissional com a Joaodev41")
• Fully responsive with smooth animations, hover effects, subtle glows, and a grid background pattern for visual depth

You'll want to update the WhatsApp phone number in components/whatsapp-button.tsx and components/sections/footer.tsx — replace 5500000000000 with the actual number.

Now I have full context. Let me generate the background images and then make all the changes. The WhatsApp number 75 99801-5021 translates to +5575998015021.

Now let me update the WhatsApp number, add background images, make cards more 3D, and add the service detail modals. Let me do all the edits:

Now let me update the Hero with background image and 3D elements:

Now the most important one -- the services section with "Saiba mais" that opens detail modals about each service:

Now update the remaining sections with 3D effects and backgrounds:

Now update the technology section code block with a 3D tilt effect:

Now update the bonus section with 3D on the app mockup:

Also update the feature cards in bonus to have subtle 3D hover:

Here's a summary of all the changes made:

1. WhatsApp number updated to 5575998015021 (75 99801-5021) in both the WhatsApp button component and the footer link.
2. Subtle background images added to 4 sections (Hero, Problems, Services, CTA) -- each has a low-opacity niche-related image with a gradient overlay on top so the content remains readable.
3. 3D effects throughout: Cards now float up on hover with hover:-translate-y-2 and drop shadows (hover:shadow-xl). The hero mockup, code block in technology, and app mockup in bonus all use CSS perspective with rotateY/rotateX transforms that flatten on hover. Icon containers also lift independently with their own shadow effects.
4. Services "Saiba mais" modal: Each service now opens a detailed modal with a headline, description, feature checklist with checkmarks, an "Ideal para" section, and a WhatsApp CTA button to convert directly from the modal.
