Tech-Forward

Create a full-screen hero section landing page using React, Vite, and Framer Motion (`motion` package). Use plain CSS (no Tailwind). The font is Inter (weights 300, 400, 500, 600) from Google Fonts. The design is minimal black-and-white with a full-viewport background video.

**Stack:** React 19, Vite, `motion` (framer-motion), `lucide-react` (for the Plus icon).

**Layout:**
- Full viewport height (`min-height: 100vh`), white background, flex column with `justify-content: space-between`
- Fixed navbar at top (z-index 50, pointer-events none on the nav itself, auto on children)
- Absolutely positioned full-screen video behind everything (z-index 0)
- Footer content pinned to bottom (z-index 30) with a white gradient fade-up background

**Navbar (fixed, top):**
- Left side contains:
  1. Logo: custom SVG icon (two rotated rounded rectangles at -35deg, black fill) + brand text "NeuralKinetics" (hidden on mobile, shown on desktop 768px+)
  2. Menu button: black pill with white circle containing a Plus icon (lucide, size 12, strokeWidth 3) + "Menu" text (11px, white)
  3. Tags pill: light gray (#F4F4F6) rounded-full container with two text labels "Advanced Bionics" and "Cognitive AI" (hidden on mobile, shown on desktop)
- Right side contains:
  - A light gray pill with a black circle button (containing a 4-dot grid SVG icon) + label "Adaptive Systems" (hidden on mobile)

**Background Video:**
- URL: `https://d8j0ntlcm91z4.cloudfront.net/user_38xzZboKViGWJOttwIXH07lWA1P/hf_20260508_215831_c6a8989c-d716-4d8d-8745-e972a2eec711.mp4`
- autoPlay, muted, playsInline, object-fit: cover
- On mobile: video wrapper is 80% width and 80% height (centered)
- On desktop (768px+): video wrapper is 100% width and 100% height

**Footer content (bottom, over gradient):**
- Background: `linear-gradient(to top, #ffffff 0%, rgba(255,255,255,0.8) 50%, transparent 100%)`
- On mobile: stacks vertically. On desktop: row layout, items aligned to bottom.
- Left block:
  1. Subtitle line: small black dot (8px circle) + "Best digital banking card 2026" (13px, 55% opacity black)
  2. Heading: "One Card, Zero / Limits. Worldwide." on two lines. Font-weight 300, clamp(2rem, 8vw, 4.5rem) on mobile, clamp(2.5rem, 5.5vw, 4.5rem) on desktop, letter-spacing -0.03em, line-height 1
  3. Two buttons: "See Features" (black pill, white text, 13px) and "How It Works" (transparent with dark border rgba(0,0,0,0.35), 13px)
- Right block: Three tag pills "Neuromorphic", "AGI", "Cybernetics" (white bg, light border rgba(0,0,0,0.12), 11px, rounded-full)

**Animations (using `motion` from 'motion/react'):**
- Navbar: slides down from y:-16, opacity 0 to visible. Duration 0.8s, ease [0.16, 1, 0.3, 1]
- Video: fades in from opacity 0 + scale 1.05 to opacity 1 + scale 1. Duration 1.8s
- Footer wrapper: slides up from y:20, delay 0.5s, duration 1s
- Subtitle: slides up from y:16, delay 0.6s, duration 0.8s
- Heading: slides up from y:20, delay 0.8s, duration 0.8s
- Buttons: slides up from y:16, delay 1.0s, duration 0.8s
- All use ease: [0.16, 1, 0.3, 1]

**Responsive (mobile-first, breakpoint at 768px):**
- Mobile: navbar padding 16px, smaller buttons (28px circles), brand text hidden, tags hidden, right label hidden, footer stacks vertically, video at 80% size
- Desktop (768px+): navbar padding 24px 32px, larger buttons (32px circles), all text/tags visible, footer is row layout, video fills 100%
