/* ---------- Sections over a photograph (home page) ----------
   Photos are saved already muted, so no CSS filter runs while scrolling. These sections stay dark in both

   - Plans: NASA Earth Observatory, "City Lights of the United States 2012" (public domain), 75% saturation, 85%
     brightness. The whole photo spans the screen width from the top of the section so the outline of the United
     States reads at a glance, then fades into the background (the photo is 3:2, so its height is 66.7vw).
   - Final call to action: U.S. Department of Energy, "Gas centrifuge cascade" (public domain), 70% saturation,
