/* Q.E.D. ─ the sheet.
   Built to his design picture: a black poster field, one accent, one grey halftone mass, a
   50.5% column split, a display lockup at ten times the body size, letterspaced mono labels and
   curly brace annotations. The accent and the materials are his own X plates: gold on stone. */
