The classic highly-prized 'Linear style' background grid. Employs a pure CSS repeating SVG pattern masked by an overlapping radial glow.
Implement a 'Linear-style' extremely subtle background grid. Create a 32x32px repeating SVG pattern using pure CSS set to a faint #ffffff opacity 0.04 against an ultra-dark background (#0a0a0a). Crucially, overlay a radial-gradient mask from the top center that softly fades the grid out towards the edges.
