   KOLOB 𐐗𐐄𐐢𐐉𐐒 — ink and paper
   The 1985 hymnbook: cream stock, deep green ink, letterpress rules, cloth
   cover. Green academia — classical sheet music, liner notes, a chapel
   library. Airy, open, minimal. NO neon, NO chrome, NO CRT. The one glow in
   the whole interface lives in the Liahona dial (drawn by the canvas).
