/* mxplx — a memex for quotes and ideas.
 *
 * Design: ink on cool paper, a reading serif for the quotes, a plain grotesk
 * for the interface. The only color is the four element glyphs —
 * meme (blue hexagon), reference (red square), triple (cyan triangle),
 * schema (green circle) — used as marginal marks everywhere.
