Bold Studio

Build a fullscreen hero landing page for a creative agency called "VANGUARD" using React, Tailwind CSS, and Vite. The page should be a single viewport-height section with a looping background video and all content overlaid on top.

**Background video:**
Use this exact CloudFront URL as a fullscreen `<video>` element with `autoPlay`, `muted`, `loop`, and `playsInline` attributes, set to `object-cover` to fill the entire viewport:

```

**Fonts (loaded in index.html):**
1. "FSP DEMO - PODIUM Sharp 4.11" from `https://db.onlinewebfonts.com/c/8b75d9dcff6a48c35a46656192adf019?family=FSP+DEMO+-+PODIUM+Sharp+4.11` -- used for the brand name and main heading. Create a `.font-podium` utility class for it and register it in tailwind.config.js as `fontFamily.podium`.
2. "Inter" from Google Fonts (weights 400, 500, 600, 700) -- used for body text, nav links, stats, and CTAs. Register it in tailwind.config.js as `fontFamily.inter`.

**Icons:** Use `lucide-react` for all icons: `ArrowUpRight`, `Award`, `Crown`, and `X`.

**Navbar:**
- Horizontal bar at the top with responsive padding (`px-6 sm:px-10 lg:px-16`, `py-5 lg:py-7`).
- Left: brand name "VANGUARD" in `font-podium`, white, bold, uppercase, `text-2xl sm:text-3xl`, `tracking-wider`.
- Center (hidden below `md`): four nav links -- "Projects", "Studio", "Offerings", "Inquire" -- in `font-inter`, `text-sm`, `text-white/80`, `tracking-widest`, uppercase, with `hover:text-white` transition.
- Right (hidden below `md`): a "GET IN TOUCH" link with an `ArrowUpRight` icon, styled as a bordered button (`border border-white/30 hover:border-white/60`, `px-6 py-3`, `text-xs`, `tracking-widest`, uppercase, `hover:bg-white/10`).
- Right (visible below `md`): a hamburger button made of three white `div` bars (`w-6 h-0.5`, `w-6 h-0.5`, `w-4 h-0.5` with `space-y-1.5`).

**Mobile Menu Overlay (below `md` only):**
- Fixed fullscreen overlay (`fixed inset-0 z-50`) with `bg-black/95 backdrop-blur-sm`.
- Toggles visibility via React `useState` -- when open: `opacity-100 visible`, when closed: `opacity-0 invisible`, with `transition-all duration-500`.
- Header row matches the navbar: brand name on left, `X` close icon on right.
- Centered vertically: each of the 4 nav links rendered in `font-podium`, `text-4xl sm:text-5xl`, white, uppercase, with staggered entrance animations using inline `style` -- each item gets `transitionDelay: i * 80 + 100ms`, `opacity` and `translateY(20px)` transitions based on the open state.
- Below the links: a "GET IN TOUCH" bordered button with the same staggered animation pattern.
- All links call `setMenuOpen(false)` on click.

**Hero Content (vertically centered, left-aligned):**
All hero elements use staggered `animate-fade-up` animations (defined in CSS as `@keyframes fade-up` translating from `translateY(30px), opacity:0` to `translateY(0), opacity:1` over `0.8s ease-out`). Each successive element has an additional `0.2s` delay. Elements start with `opacity: 0` and use `animation-fill-mode: forwards`.

1. **Tagline:** A `Crown` icon (lucide, `w-4 h-4`, `text-white/70`) followed by "World-Class Digital Collective" in `text-white/70`, `text-xs sm:text-sm`, `font-inter`, `tracking-[0.3em]`, uppercase. Uses `animate-fade-up` (no delay). Has `mb-6 lg:mb-8`.

2. **Main Heading:** Three lines in `font-podium`, white, uppercase, `leading-[0.92]`, `tracking-tight`, each using `text-[clamp(2.8rem,8vw,7rem)]`:
   - "Design."
   - "Disrupt."
   - "Conquer."
   Uses `animate-fade-up-delay-1` (0.2s delay).

3. **Subtext:** "We build fierce brand identities" (line break) "that don't just turn heads --" then bold white "they lead." in `text-white/70`, `text-sm sm:text-base`, `font-inter`, `leading-relaxed`, `max-w-md`. Uses `animate-fade-up-delay-2` (0.4s delay). `mt-6 lg:mt-8`.

4. **CTA Row:** Uses `animate-fade-up-delay-3` (0.6s delay), `mt-8 lg:mt-10`, `flex flex-wrap items-center gap-4 sm:gap-6`.
   - Black button "SEE OUR WORK" with `ArrowUpRight` icon. `bg-black hover:bg-neutral-900`, `px-5 sm:px-7 py-3 sm:py-4`, `text-[11px] sm:text-xs`, `tracking-widest`, uppercase. Arrow has `group-hover:translate-x-0.5 group-hover:-translate-y-0.5` transition.
   - Beside it (hidden on mobile, `hidden sm:flex`): an `Award` icon (`w-8 h-8`, `text-white/50`) with two lines of text: "Top-Rated" / "Brand Studio" in `text-white/60`, `text-xs`, `tracking-wider`, uppercase.

5. **Stats Row:** Uses `animate-fade-up-delay-4` (0.8s delay), `mt-8 sm:mt-10 lg:mt-14`, `flex flex-wrap gap-6 sm:gap-12 lg:gap-16`. Three stats:
   - "250+" / "Brands Transformed"
   - "95%" / "Client Retention"
   - "10+" / "Years in the Game"
   Values in `font-inter`, white, `text-2xl sm:text-4xl lg:text-5xl`, bold, `tracking-tight`. Labels in `text-white/50`, `text-[9px] sm:text-xs`, `tracking-widest`, uppercase, `mt-1`.

**CSS Animations (defined in index.css under `@layer utilities`):**
```css
@keyframes fade-up {
  from { opacity: 0; transform: translateY(30px); }
  to { opacity: 1; transform: translateY(0); }
}
@keyframes fade-in {
  from { opacity: 0; }
  to { opacity: 1; }
}
@keyframes scale-in {
  from { opacity: 0; transform: scale(0.9); }
  to { opacity: 1; transform: scale(1); }
}
```
With classes: `.animate-fade-up` (0s delay), `.animate-fade-up-delay-1` through `.animate-fade-up-delay-4` (0.2s increments, starting `opacity: 0`), `.animate-fade-in`, `.animate-fade-in-delay`.

**Responsive behavior:**
- Full layout is mobile-first with breakpoints at `sm` (640px), `md` (768px), and `lg` (1024px).
- Nav links and "GET IN TOUCH" button show at `md`+; hamburger shows below `md`.
- Award badge hides on mobile (`hidden sm:flex`).
- All text sizes, paddings, gaps, and margins scale up through `sm:` and `lg:` prefixes.
- Stats and CTA row use `flex-wrap` to prevent overflow on small screens.

Make everything fully mobile responsive. Use a single `App.tsx` component with `useState` for the menu toggle. No routing needed.
