Network Hero

Create a single-page React + Vite landing page for "Marketeam" -- a marketing talent platform. Use Inter (400, 500, 600, 700) and Urbanist (600, 700) from Google Fonts. The page is a full-viewport hero with a header, left content area, right animated circles visualization, and a bottom logo ticker strip.

### Background

Full-page background image covering the entire viewport:

```
Applied as `background: url(...) center center / cover no-repeat` on the root `.app` container.

### Header

- Flexbox row, `justify-content: space-between`, padding `24px 64px`, max-width `1920px`, centered.
- **Left side**: Logo image + nav links
  - Logo: `<img>` with height 32px from: `https://polo-pecan-73837341.figma.site/_assets/v11/17ae538989a509947a8de3892c644664895e69b1.png`
  - Nav links: "Your Team", "Solutions", "Blog", "Pricing" -- color `#000000`, 15px, font-weight 400, with underline animation on hover (scaleX from 0 to 1, transform-origin left, 0.3s ease).
- **Right side**: "Log In" link + "Join Now" button
  - Log In: color `#ffffff`, 15px, weight 500, same underline hover as nav but white.
  - Join Now: pill button (border-radius 50px), black bg (`#000000`), white text, padding `12px 26px`, 15px, weight 500. On hover a `#A068FF` fill slides in from left using `::after` with `translateX(-100%)` to `translateX(0)`, cubic-bezier(0.22, 1, 0.36, 1), 0.4s. Button uses `overflow: hidden`.
  - The button is wrapped in a `.btn-border-wrap` div that has a rotating conic-gradient border using `::before` with `inset: -3px`, `padding: 3px`, mask technique for border-only effect. The gradient is: `conic-gradient(from var(--border-angle), #A068FF, #070319, #A068FF, #070319, #A068FF)`. It rotates via CSS `@property --border-angle` from `0deg` to `360deg` in 3s linear infinite.

### Hero Left

- `flex: 0 1 600px`, `padding-top: 40px`
- **Heading**: Typewriter effect, font Urbanist, 64px, weight 600, line-height 64px, letter-spacing -1.5px. Text: "Unlock Top Marketing Talent You Thought Was Out of Reach -- Now Just One Click Away!". The first 67 characters are colored `#000000`, the rest `#ffffff`. A blinking purple cursor (`#A068FF`) appears during typing. Typing speed: 35ms per character, starts after 400ms delay.
- **"Start Project" button**: Same pill style as Join Now but slightly larger (padding `14px 28px`, 16px), bg `#060218`. Has a right-arrow chevron SVG icon (18x18). Hover fill slides from right (`translateX(100%)` to `translateX(0)`). Also wrapped in `.btn-border-wrap` with the same rotating gradient border. Appears after typing finishes (animation-delay 3.2s).
- **Cursor element**: A purple cursor icon (SVG: pointer arrow filled `#A068FF`) + "David" label (pill badge, bg `#A068FF`, white text, 16px, weight 500, padding `8px 16px`, border-radius 20px). Positioned `margin-left: 290px`, `margin-top: 40px`. Appears with animation-delay 3.6s.

### Hero Right -- Circles Visualization

- Container: `720x720px`, centered.
- 4 concentric circles (orbits), each rotating slowly:
  - Orbit 1 (innermost): 353px diameter, spins left (counterclockwise) 30s
  - Orbit 2: 501px diameter, spins right 40s
  - Orbit 3: 649px diameter, spins right 50s
  - Orbit 4 (outermost): 797px diameter, spins left 60s
- Each circle has a 1px gradient border: `linear-gradient(180deg, rgba(217, 161, 255, 0) 0%, rgba(217, 161, 255, 1) 43%, rgba(217, 161, 255, 0) 100%)` applied via the mask technique.
- **Center circle (orbit-1)**: Displays an animated count-up number "20k+" (Urbanist 64px, weight 500) and "Specialists" label (Urbanist 16px, weight 600). Counter-rotates to stay upright.
- **Avatars** placed on orbits using `transform: translate(-50%, -50%) rotate(Xdeg) translate(radius) rotate(-Xdeg)`:
  - Avatar images (58px default, some 78px/88px) from these URLs:

### Technical Details

- React (useState, useEffect, useRef), Vite build
- Custom `useCountUp` hook: animates 0 to 20 over 2s with easeOutCubic, starts after 1.2s delay
- `TypewriterHeading` component: types char by char at configurable speed
- CSS `@property --border-angle` for the animated border gradient
- No external animation libraries -- pure CSS animations + JS for typewriter/counter
