   THE SLOW BUILDS - editorial system v2 (2026-06-14 PM)
   Two movements:
   1) THE PREMISE - a quiet first-person aside about the day job.
   2) THE LAB - a sticky-stack "syllabus" of builds that probe the future;
      each card's big text is its thesis, the name rides the peeking spine;
      experimentswith.tech is the inverted finale. Brick wanders, quietly.
   Paper + ink, ONE warm rust accent. Color = emphasis, not decoration.
