I've created a component that uses CSS radial-gradient to create the dotted grid pattern. Here's what's happening:

1. The outer div sets up a full-screen container with the dark blue background color
2. The inner div uses absolute positioning to cover the entire container
3. The radial-gradient creates white dots that are 2px in size
4. The backgroundSize property spaces the dots 24px apart both horizontally and vertically
5. A slight opacity is added to match the softer appearance of the dots in the reference image

You can adjust the dot size, spacing, and colors by modifying the corresponding values in the style object. For example, to make the dots larger or smaller, change the 2px value in the radial-gradient. To adjust the spacing, modify the backgroundSize value.

I've updated the component with:

1. Changed the background color to Deep Blue (#00008B)
2. Changed the dot color to Light Cream (#FFFDD0)
3. Slightly increased the opacity to 0.9 to make the dots more visible against the darker background

The Light Cream color creates a softer, more pleasant contrast compared to pure white, while still maintaining excellent readability. The color combination gives the grid a more sophisticated and elegant appearance while reducing eye strain.
