Colophon

One warm hue, 40°, runs from the paper to the ink, with three weights of rule between them. Ink is the only accent. In dark mode the paper goes to near-black and the footer band turns to bone, so there is still exactly one reversed band.

The head on the home page is a marble woman carved in Greece between 300 and 200 BCE, drawn as a survey map of its own light: 120 lines, each following one level of brightness across the stone. Lines run heavier where the marble falls into shadow, every fourth one a little heavier still, and the brightest levels are left as open paper, the way an engraver leaves the highlights. By night the polarity turns: the lit marble takes the ink and the shadows stay open. It is drawn live in WebGL. The levels rise out of the ink when you arrive and drift a moment before they settle; a mouse wakes them and carries a loupe that doubles them; on the way down the page they spread and drop away. Cut down to a few dozen lines, it is the emblem beside the name.
