   Engine reference stylesheet — BUILD_GUIDE §5 made concrete. v3.
   Thesis: A DOCUMENT, NOT A UI (motherfuckingwebsite discipline + Gestalt).
     · One readable column. Grouping comes from whitespace and proximity,
       never from boxes. Borders exist only where a table needs ruling.
     · Two voices: Archivo for the writer, IBM Plex Mono for the instrument
       (figures, dates, run numbers, verdicts). Provenance sits directly
       under the fact it vouches for — closeness IS the grouping.
     · Color means data, nothing else. One ink button per page. Everything
       else is text.
     · The moat is visible: history leads, archives are public, donated
       counts are part of the dataset, every fact carries a cite string.
