Now let me read the remaining component files to understand where inline color classes are being used instead of semantic tokens:

Good. I have a clear picture now. The core problem is that oklch() colors are not supported in older browsers (notably Safari < 15.4 and some Android browsers), causing semantic tokens like text-primary to fall back to the browser default (black/blue) instead of the intended green. I need to:

1. Replace oklch() with universally compatible hsl() values in globals.css
2. Add a ThemeProvider with next-themes for dark mode
3. Add a Sun/Moon toggle button in the header

Now update layout.tsx to wrap with ThemeProvider:

Now read and update the theme-provider to ensure it's the next-themes version:

The ThemeProvider is already correct. Now add the dark mode toggle to the header:

Two key fixes were made:

1. Color compatibility — All oklch() values in globals.css were replaced with universally supported hsl() values. oklch is unsupported in older Safari and many Android browsers, which caused colors to silently fail. The @theme inline block now wraps each token in hsl() so Tailwind classes like text-primary and bg-muted resolve correctly on every device.
2. Dark mode toggle — Added a ThemeToggle component inside the header using next-themes' useTheme hook. It shows a Sun icon in dark mode and a Moon icon in light mode, with a mounted guard to prevent hydration mismatches. The layout is now wrapped in ThemeProvider with attribute="class" and enableSystem so it respects the user's OS preference by default.

Now I understand the full scope. Let me read the current components to fix the button issues and implement the upgrades:

Now I'll implement all the upgrades. The issue with buttons not working is likely due to hydration mismatches or the useTheme hook being called before mounting. Let me fix the header with the logo, update footer, create the village layout carousel, and create the reviews section.

Now update the page to include the new sections in the correct order:

I've implemented all three upgrades and fixed the button issues:

Fixes:

• Changed theme to resolvedTheme in the theme toggle for reliable dark/light detection
• Replaced Link with native <a> tags and added scrollToSection handlers for smooth scrolling to anchor sections
• Added type="button" and cursor-pointer to all interactive buttons to ensure consistent click behavior

Upgrade 1 (Logo): Header and footer now display the moduvo SVG logo via next/image with proper sizing and alt text.

Upgrade 2 (Village Layout): New section with a touch-responsive image carousel featuring the watercolor blueprint, aerial view, and lifestyle images. Includes hover-visible navigation arrows, animated pagination dots, and a features list with icons for the 10 units, gym container, laundry hub, and fire pit.

Upgrade 3 (Reviews): Added a testimonial grid with three pre-filled 5-star reviews, plus an interactive review form with a hover/click star selector, name input, textarea, and a smooth fade-in success message on submission.
