/* v10 · "A working map of how I think"
   Written for a senior reader with little time: an editorial document, not a show. Ivory paper, graphite
   ink, one serif for thought and one sans for facts, hairline rules, roman-numeral sections. Colour is used
   only to code the map: reasoning (ink blue), people (oxblood), craft (ochre). Motion is slow and rare. */
