I broke the landing page's background in D6003 by adding a CSS selector that applied globally to html and body.

Turns out doing it right is a bit harder. In order to avoid needing dynamic imports, I needed to stop relying on html and body for styling, as they appear above #react-root. To make that happen, I had to move the background styling to inner divs, which required moving some CSS attributes around to get everything to look right.

Make sure http://localhost:3000/commlanding/ has the proper background (both layers of CSS background, plus the stars, and with scrolling looking right) and that http://localhost:3000/commlanding/siwe just has a gray background
