Adjusted netflix-grid.tsx: Modified container classes for `CategoryRow` to ensure videos do not overflow horizontally (`max-w-6xl mx-auto` and `px-4`). Changed navigation arrows to a gradient track style positioned at the edges of the container, replacing circular buttons. Updated video card widths for various screen sizes to `w-280px` to `w-340px`.
