- Around line 41-49: The current markup nests a semantic <button> (Button
component) inside a Next.js <Link> which renders an <a>, producing invalid HTML;
fix it by using Button's asChild prop and moving the Link to be the Button's
child so Button forwards its styles/props onto the Link's anchor element (i.e.,
change to <Button asChild ...><Link href="/">…</Link></Button>), preserving all
existing Button props (variant, className, icons/text) and keeping the same
visual layout and accessibility.

Stale comment: pt-32 doesn't match the applied pt-8.
The comment claims the padding-top is synced to pt-32 (matching the Hero section), but the actual class is pt-8. Update the comment or the class to be consistent.

Add tailwindcss-animate import to globals.css.
The tailwindcss-animate plugin has been installed, but Tailwind v4 with @tailwindcss/postcss requires explicit import. Add this line to ./src/app/globals.css after the existing @import "tailwindcss":
`@import` "tailwindcss-animate";Without this, the animation utility classes (animate-in, fade-in, slide-in-from-*, zoom-in) on lines 18, 27, 34, 40, and 62 will not render.

window.history.back() is a no-op when there's no browser history.
If the user navigates directly to a 404 URL (e.g., via a bookmarked broken link), the history stack is empty and the "Go Back" button silently does nothing. Consider disabling it or hiding it when there's no previous entry, or replacing it with a fallback redirect.
