   Shades near the automaker's own, on purpose approximate: deep navy,
   light blue, white ink, a red stamp. Barlow Condensed for titles,
   JetBrains Mono for everything else (the reader codes; the text looks
   like what comes out of the cable). Plain CSS, no build.
   The experience (stage, chapters, cards) lives in exp.css.
