/* /openai-math-explorer: an explorer for OpenAI's mathematics release.
   Set like a journal index: STIX Two Text for reading (it sits naturally beside
   KaTeX's Computer Modern), IBM Plex Sans for interface text and figures, blue-
   black ink on white, and the teal link ink of OpenAI's own catalog PDF. The
   five area hues were validated as a set (all pairs, light surface); the map
   also gives every area its own marker shape so color is never the only cue. */
