Restructure video data storage by moving hardcoded arrays to an external JSON file.
Implement async data loading functions in both script.js and video.js to fetch data from the new JSON file.
This improves maintainability and makes it easier to update video content without modifying source code.
Add new video player page with responsive layout, video details display, and comments section. Includes video player, channel info, like/dislike buttons, and interactive elements. Also add null checks in main script to prevent errors when elements are missing.
