Let me read the actual files to debug what's going wrong.

I see the issue. The project has Tailwind v3 installed but the PostCSS config is using the Tailwind v4 plugin format (tailwindcss: {} instead of @tailwindcss/postcss). Also the CSS uses the old @tailwind directives which conflict. Let me also check if there's a conflict with the @tailwindcss/postcss dev dependency. The project has both tailwindcss: ^3.4.17 and @tailwindcss/postcss: ^4.1.13 -- that's a conflict. Let me fix the PostCSS config to use the correct Tailwind v3 setup since the tailwind.config.ts is written for v3.

Now let me also fix the package.json -- the @tailwindcss/postcss v4 dependency is conflicting with the Tailwind v3 setup. Let me remove it and ensure we have the right deps.

Now let me also rewrite the valentine component to be simpler and more robust, removing the next/image dependency (which can cause issues with unoptimized images) and using a plain <img> tag instead:

The issue was a dependency conflict: the project had both Tailwind v3 (tailwindcss: ^3.4.17) and a Tailwind v4 PostCSS plugin (@tailwindcss/postcss: ^4.1.13), which was causing the build to break. I removed the v4 PostCSS dependency, added autoprefixer to the PostCSS config for proper v3 support, and also simplified the valentine component to use a plain <img> tag instead of next/image to avoid any image optimization config issues. The site should now load properly with the retro pink theme, runaway "No" button, and confetti celebration.

Now I can see all the files clearly. The code all looks correct syntactically. The issue might be that the @import url() for the Google Font is placed after the @tailwind directives, which can cause PostCSS processing issues. Also, the layout is missing the font import setup. Let me check if there's an _app or any other conflicting file, and also verify the image exists:

The image file doesn't exist in public/ and the app files aren't being found by glob -- that's the issue. The files might not have been properly written. Let me verify:

I see there's a styles/globals.css file too that could be conflicting. Let me also check if the next.config.mjs has any issues:

Found it. The @import url(...) in app/globals.css is placed after the @tailwind directives. PostCSS requires @import statements to come first, otherwise it throws an error and the whole page fails to load. Let me fix the globals.css by moving the import to the top:

Good, now I need to load the font via next/font/google in the layout instead. And also add back the custom CSS animations and the .font-retro / .pixel-border classes:

Now update the layout to load the "Press Start 2P" font properly via next/font/google:

Now update the .font-retro class in globals.css to use the CSS variable:

I see the problem -- all the animations and classes are duplicated. The file has everything twice. Let me rewrite the entire globals.css cleanly:

Now let me also verify the valentine component is clean and add a debug log to check if it renders:

Good, the valentine component looks fine. Let me also verify the page.tsx is correct:

Let me verify the image file is accessible:

The image exists and looks great. The root causes were: (1) the @import url() for the Google Font was placed after @tailwind directives, which PostCSS doesn't allow, and (2) all the CSS animations and utility classes were duplicated in the file causing parse errors. I've cleaned up globals.css to remove the problematic @import and duplicates, and switched to loading the "Press Start 2P" font properly via next/font/google in the layout. The site should now load correctly with the cute pixel bear, retro pink theme, runaway "No" button, and confetti celebration.
