/* barackliu.org — 2026-09 redesign: "drafting table".
   Light: cool graph paper, graphite ink, one vermilion accent.
   Dark: blueprint navy with chalk-white lines.
   Display type is a sharp grotesque; labels, dates and numbers are monospaced, like the
   annotations on an engineering drawing. Sections are numbered like drawing sheets. */
