/* Layout shared by every page. styles/orbit.css sets the tokens below and adds the
   look (the "Orbit" style Mara chose on 23 October 2026). The palette is the CV's (Misc/CV/tex/cv.sty):
   burgundy #A61C41 and muted magenta #9E5090, which differ in lightness as well as
   hue so they stay distinct for red-green color vision. */
