Haz tuyo «Código de sección hero con navbar de cristal y vídeo de fondo»

Create a full-screen hero section in React + TypeScript + Tailwind CSS (Vite) with a fullscreen background video, a floating "liquid glass" navigation bar, an animated character-by-character heading, and a bottom liquid-glass tagline pill. Stack / Setup: React 18 + TypeScript + Vite Tailwind CSS (default config, no theme extensions) No extra libraries (no framer-motion, no icon libs needed for this section) Font: 'Helvetica Neue', Helvetica, Arial, sans-serif, weight 400, antialiased Global CSS (src/index.css): @tailwind base; @tailwind components; @tailwind utilities; body { font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; font-weight: 400; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; } .liquid-glass { background: rgba(0, 0, 0, 0.4); background-blend-mode: luminosity; backdrop-filter: blur(4px); -webkit-backdrop-filter: blur(4px); border: none; box-shadow: inset 0 1px 1px rgba(255, 255, 255, 0.1); position: relative; overflow: hidden; } .liquid-glass::before { content: ''; position: absolute; inset: 0; border-radius: inherit; padding: 1.4px; background: linear-gradient(180deg, rgba(255,255,255,0.3) 0%, rgba(255,255,255,0.1) 20%, rgba(255,255,255,0) 40%, rgba(255,255,255,0) 60%, rgba(255,255,255,0.1) 80%, rgba(255,255,255,0.3) 100%); -webkit-mask: linear-gradient(#fff 0 0) content-box, linear-gradient(#fff 0 0); -webkit-mask-composite: xor; mask-composite: exclude; pointer-events: none; } Components: AnimatedHeading — splits text into characters, each <span> is inline-block with transition-all duration-500. Starts at opacity: 0, translateX(-18px) and animates to opacity: 1, translateX(0) with a per-character transitionDelay of lineIndex * line.length * charDelay + charIndex * charDelay ms. Supports multi-line via \n split, each line wrapped in <div className="flex flex-wrap justify-center">. Starts after delay ms via setTimeout. Preserves spaces using \u00A0. FadeIn — wraps children in a div with transition-opacity, toggles opacity 0 -> 1 after delay ms, transitionDuration configurable (default 800ms).
