VertexAI Hero

Build a React + TypeScript + Vite hero section for a fictional brand "VertexAI". Render a full-viewport hero with a looping background video, a frosted-glass navbar, a centered headline using mixed sans + italic-serif typography, and a footer row with a description on the left and tag buttons on the right. Follow this spec verbatim — class names, values, copy, SVG paths, padding, opacity, and all CSS must match exactly.

Project setup
React 19 + TypeScript + Vite. Files: index.html, src/main.tsx, src/App.tsx, src/App.css, src/index.css, src/components/Navbar.tsx, src/components/Navbar.css, src/components/HeroContent.tsx, src/components/HeroContent.css, src/components/FooterElements.tsx, src/components/FooterElements.css.
main.tsx mounts <App /> inside <StrictMode> and imports ./index.css.

App.tsx
import './App.css'
import Navbar from './components/Navbar'
import HeroContent from './components/HeroContent'
import FooterElements from './components/FooterElements'

function App() {
  return (
    <main className="hero-section">

The video element must include autoPlay, loop, muted, playsInline (lowercase HTML attributes) so it autoplays inline on every browser. No overlay — the video shows through directly behind everything.

Navbar.tsx

The navbar consists of two parts: a logo block on the left (4-circle SVG mark + brand wordmark "VertexAI") and a darkened glass pill on the right that combines the nav links and the white Login button. The pill uses warm dark fill rgba(20, 18, 16, 0.42) plus an 18px backdrop-blur and a 1px white-8% border, with a border-radius of 16px (rounded rectangle, not a true pill). The Login button uses a tighter 12px radius.

Animations / interactions
All buttons inherit transition: all 0.3s ease from the global button selector.
Login button: hover lifts 1px (translateY(-1px)) and dims white to 90%.
CTA "Start free decoration": hover scales to 1.05 and intensifies the white glow shadow.
Tag buttons: hover gains the --glass-bg fill and the border brightens to full white.
Icon button (arrow): hover rotates 45° and gains the glass background — the arrow appears to flip toward bottom-right.
Nav links: hover transitions text color from --secondary-white (white 70%) to --primary-white.
Background video: loops continuously, muted, autoplays inline, object-fit: cover over the full viewport.
Acceptance checklist
Hero section is exactly 100vw × 100vh, with a 20px outer padding, content distributed top/middle/bottom via flexbox.
Looping CloudFront video plays behind everything at z-index -1 with no tint or overlay.
Top row: left-side logo (4 white-80% circles SVG + "VertexAI" wordmark) and right-side dark glass nav pill containing 4 nav links + white Login button (12px radius).
Middle: three-line headline as specified, with Cormorant Garamond italic only on "Redefine space"; centered; clamp(36px, 4.4vw, 72px); line-height 0.95. White CTA "Start free decoration" with padding: 15px 25px, border-radius: 12px, soft shadow.
Bottom: 4-line description on the left at 15px / 1.18 line-height, opacity 0.8; right column has "Solutions for complex spaces" stacked over a row of [arrow icon button] + "Conversational & Action". All three buttons use a 16px-radius outlined glass treatment with a 0.75px white border. The footer row sits 36px above the bottom edge.
Below 900px viewport, nav links hide and footer stacks vertically; below 768px the section padding becomes 30px 20px and headline letter-spacing tightens to -1px.
