Walkthrough

This PR adds a new Projects section to the home page with a responsive carousel component. The carousel UI component provides Embla-based slide navigation with keyboard support and dot pagination. CardCaption is extended to accept rich content. The Projects section uses both components to display featured projects with responsive layouts. The home page is updated to integrate the new section with adjusted spacing.

Changes

Projects Section with Carousel UI

Layer / File(s)	Summary
Carousel UI component src/components/ui/carousel.tsx	Defines CarouselApi, Carousel, CarouselContent, CarouselItem, and CarouselDots components using embla-carousel-react. Manages Embla initialization, scroll state, keyboard navigation via arrow keys, and exposes optional setApi callback. Uses React context to share refs and navigation state with subcomponents.
CardCaption enrichment for rich content src/components/card-caption.tsx	Extends CardCaption to accept ReactNode instead of only string, adds optional className prop for the root Card, and conditionally wraps string captions in <p> while rendering non-string nodes directly.
Projects section component src/components/home/projects.tsx	Defines Projects component with featured project data. Renders responsive "15+ Projects" section with static CardCaption grid on desktop/tablet and Carousel with CarouselItem slides and CarouselDots pagination on mobile, plus a primary call-to-action button.
Home page layout integration src/app/page.tsx, src/components/home/hero.tsx, src/components/home/materials.tsx, package.json	Imports and inserts Projects component into home page between Materials and AboutUs. Updates Hero section top padding from pt-24 to pt-67 and removes sm:pt-67. Changes Materials section padding from sm:py-28 to universal py-28. Adds embla-carousel-react@^8.6.0 dependency.

src/components/ui/carousel.tsx (1)

150-161: ⚡ Quick win

Consider using a more appropriate element than <fieldset> for carousel items.

The <fieldset> element is semantically intended for grouping form controls with a <legend>. For carousel slides, a <div> is more semantically appropriate. If the carousel structure uses a list pattern, consider <li> within a <ul> parent.

♻️ Proposed refactor to use div

-    <fieldset
+    <div
       aria-roledescription="slide"
       data-slot="carousel-item"
       className={cn("min-w-0 shrink-0 grow-0 basis-full", orientation === "horizontal" ? "pl-4" : "pt-4", className)}
       {...props}
     />
