I'll build this comprehensive construction company website for "Цаст хайрхан". The screenshot shows a clean, modern construction website layout which I'll use as structural inspiration, combined with the dark premium theme specified in your document. Let me start with the foundation.

Now let me set up the theme system and update globals.css:

Good, the theme provider already exists. Let me now build all the components and pages.

Now let me update the layout and start building pages:

Now the home page:

Now the About page:

Good, I have full context on the existing code. Let me also check the existing components to understand patterns:

Now I have full context. Let me build the Projects page, then Shop, Cart, Checkout, Contact pages:

Now let me verify a few key files are correct and check for any issues:

Let me also read the footer and the about page to check everything:

Everything looks good. Let me check the debug logs to see if there are any runtime errors:

The footer has an onSubmit handler but is a server component. I need to add the "use client" directive to the footer:

Now let me mark all tasks as done:

The full "Цаст Хайрхан" construction company website is now built with all 7 pages. Here's what was created:

• Home (/) -- Hero with image grid, animated stats, scrolling marquee of service tags, services preview cards, featured projects, core values, CTA banner, and team section
• About (/about) -- Company story, breadcrumb navigation, impact section with sustainability features, values grid, and team profiles
• Services (/services) -- All 6 services displayed in detailed cards with feature checklists and icons
• Projects (/projects + /projects/[slug]) -- Filterable project gallery with category tabs, plus individual project detail pages with metadata sidebar
• Shop (/shop + /shop/[slug]) -- Product catalog with category grid, filter pills, product cards with pricing; product detail pages with variant selection, bulk pricing tiers, quantity controls, and add-to-cart
• Cart (/cart) -- Full cart management with quantity adjustment, order summary with delivery fee calculation
• Checkout (/checkout + /checkout/success) -- Customer form, payment method selection (QPay, bank transfer, bank app), order review, and success confirmation page

The site uses a gold-and-neutral color scheme with dark mode as default, Framer Motion animations, scroll-reveal effects, and a responsive layout throughout.
