Build a single-page hero section with a full-screen looping background video, liquid glass UI elements, and a dark cinematic aesthetic. Use React, TypeScript, Tailwind CSS, and Lucide React icons. Here are the exact specifications:

Background Video:

Full-screen muted autoplaying video covering the entire viewport, positioned absolutely with object-cover
Video source URL: https://d8j0ntlcm91z4.cloudfront.net/user_38xzZboKViGWJOttwIXH07lWA1P/hf_20260328_115001_bcdaa3b4-03de-47e7-ad63-ae3e392c32d4.mp4
The video is shifted down by 17% (translate-y-[17%]) so the top portion of the video is cropped -- the interesting content is in the lower portion of the frame
The video loops seamlessly with a custom JavaScript fade system (no CSS transitions): 500ms requestAnimationFrame-based fade-in on load/loop start, 500ms fade-out when 0.55 seconds remain before the video ends. A fadingOutRef boolean prevents re-triggering the fade-out from repeated timeUpdate events. On ended, opacity is set to 0, then after 100ms the video resets to currentTime = 0, plays, and fades back in. Each new fade cancels any running animation frame to prevent competing animations. Fades resume from the current opacity rather than snapping.
The outer container is min-h-screen bg-black with overflow-hidden

Font:

Import Google Font "Instrument Serif" (both regular and italic) via CSS @import url('https://fonts.googleapis.com/css2?family=Instrument+Serif:ital@0;1&display=swap')
The heading uses fontFamily: "'Instrument Serif', serif" applied via inline style

Liquid Glass CSS (.liquid-glass class):

background: rgba(255, 255, 255, 0.01) with background-blend-mode: luminosity
backdrop-filter: blur(4px) and -webkit-backdrop-filter: blur(4px)
border: none
box-shadow: inset 0 1px 1px rgba(255, 255, 255, 0.1)
position: relative; overflow: hidden
A ::before pseudo-element creates the glass border effect:
position: absolute; inset: 0; border-radius: inherit; padding: 1.4px
background: linear-gradient(180deg, rgba(255,255,255,0.45) 0%, rgba(255,255,255,0.15) 20%, rgba(255,255,255,0) 40%, rgba(255,255,255,0) 60%, rgba(255,255,255,0.15) 80%, rgba(255,255,255,0.45) 100%)
Mask trick for border-only rendering: -webkit-mask: linear-gradient(#fff 0 0) content-box, linear-gradient(#fff 0 0); -webkit-mask-composite: xor; mask-composite: exclude
pointer-events: none

Layout (all inside one full-screen flex column):

Navigation bar (relative z-20, padding pl-6 pr-6 py-6):
Inner container: rounded-full px-6 py-3 flex items-center justify-between max-w-5xl mx-auto
Left side: Logo area with a Globe icon (size 24) and text "Asme" in white, font-semibold text-lg, with gap-2
Next to the logo (with gap-8): three nav links ("Features", "Pricing", "About") -- hidden on mobile, shown on md: -- styled text-white/80 hover:text-white transition-colors text-sm font-medium
Right side (gap-4): "Sign Up" as plain white text button, "Login" as a liquid-glass rounded-full px-6 py-2 button

Hero content area (relative z-10 flex-1 flex flex-col items-center justify-center px-6 py-12 text-center -translate-y-[20%]):
Heading: "Built for the curious" -- text-5xl md:text-6xl lg:text-7xl text-white mb-8 tracking-tight whitespace-nowrap with Instrument Serif font
Below the heading, a max-w-xl w-full space-y-4 container:
Email input bar: liquid-glass rounded-full pl-6 pr-2 py-2 flex items-center gap-3. Inside: a transparent email input (placeholder: "Enter your email", text-white placeholder:text-white/40 text-base) and a white circular submit button (bg-white rounded-full p-3 text-black) containing an ArrowRight icon (size 20)
Subtitle text: text-white text-sm leading-relaxed px-4 -- "Stay updated with the latest news and insights. Subscribe to our newsletter today and never miss out on exciting updates."
Manifesto button: centered, liquid-glass rounded-full px-8 py-3 text-white text-sm font-medium hover:bg-white/5 transition-colors

Social icons footer (relative z-10 flex justify-center gap-4 pb-12):
Three circular icon buttons, each liquid-glass rounded-full p-4 text-white/80 hover:text-white hover:bg-white/5 transition-all
Icons: Instagram, Twitter, Globe (all size 20) from lucide-react
Each has an aria-label

Tech stack: Vite + React 18 + TypeScript, Tailwind CSS 3, lucide-react for all icons. Default Tailwind config with no extensions. No other UI libraries.

Reusable method

Key decisions

Check whether information hierarchy, module order, and CTA clarity all hold in the final result.

Adapt it to your subject

Extract “target result → the product name, audience, page modules, and primary button → constraints” as a reusable template for similar work.

Where it breaks

Run single-variable comparisons around module order, value proposition, and CTA placement. Record the model, cost, and failures; turn it into a Skill only after it repeats reliably.
