/* Visual language: a populated PCB read under low light — copper traces
   for structure, a phosphor-LED green for anything that is "live"
   (hover, focus, a travelling signal). Set type is bilingual-mono:
   Martian Mono for anything that reads like silkscreen/labeling,
   Fragment Mono for running text — so the whole page reads like a
   datasheet rather than a marketing template. */
