   Spencer Lab — site stylesheet

   Deep University of Lethbridge blue for the banners and footer, warm paper
   and white for reading, gold for small marks. Headings are Source Serif 4,
   text is Inter, and technical labels use JetBrains Mono. The recurring
   motifs are the white-light interferogram of the logo and faint two-source
   interference rings.
