Centered language picker

Create a high-converting, fully responsive FOOTER section for a modern website.

COMPONENT SPECIFICATIONS:
- Section Name: Centered language picker
- Category: FOOTER
- Structural Layout: centered-stacked
- Visual Design Style: minimal-swiss (light palette)
- Purpose: A minimal footer centered on a language dropdown and app badges, with a stark white background and hairline borders.

IMPLEMENTATION REQUIREMENTS:
1. Styling & Framework: Build with standard Tailwind CSS utility classes and clean semantic HTML5 / React JSX.
2. Responsive Architecture:
   - Mobile (375px - 640px): Single-column stacked layout, touch-friendly CTA buttons, and compact padding (py-12 px-4).
   - Tablet (768px - 1024px): Balanced 2-column or asymmetric grid with readable typography hierarchy.
   - Desktop (1280px - 1440px+): Full-bleed layout with maximum width (max-w-7xl), generous whitespace (py-20 lg:py-28), and refined card micro-elevations.
3. Design System & Tokens:
   - Modern typography: High-contrast headline with tight tracking (tracking-tight), readable body copy (text-sm/text-base), and uppercase eyebrow tags.
   - Borders & Accents: Subtle 1px borders (border-neutral-200 dark:border-neutral-800), smooth rounded corners (rounded-2xl), and warm amber/gold CTA gradient fills.
   - Accessibility: WCAG AA contrast compliance and crisp SVG/Lucide icon markers.
4. Output: Standalone <section> component ready to copy and drop into production.
