/* ============================================================
   COLUMEN | Midnight Monument
   Single-theme committed design: the hall at night.
   Near-black stone ground, ivory inscription, gold current; the
   lit monument stands in the dark. Chapters cut from lifted,
   veined stone bands; screens stay dark glass. Carve, don't
   card: nothing on the ground gets a fill except the bands,
   the moonlit diptych, and literal screens.
   ============================================================ */
