Editorial Light Hero — Bahçe (Garden) Theme

Create a fullscreen single-page hero section using React + Vite + Tailwind CSS + TypeScript with the following specifications:

Fonts:
Display text (headings, logo): Instrument Serif
Body text (navigation, descriptions): Inter
Import both fonts in /src/styles/fonts.css

Video Background:
URL: https://vibecodingex.com/public/video/bashce.mp4
Position: top: '300px' with inset: 'auto 0 0 0'
Implement custom fade-in/fade-out loop logic using React useEffect and useRef:
Use requestAnimationFrame to continuously monitor currentTime and duration
Fade in over 0.5s at the start (opacity 0 to 1)
Fade out over 0.5s before the end (opacity 1 to 0)
On ended event: set opacity to 0, wait 100ms, reset currentTime = 0, then play() again
This creates a seamless manual loop with smooth fade transitions
Add gradient overlays: absolute inset-0 bg-gradient-to-b from-background via-transparent to-background positioned over the video
