/* Tav app · night paper
 * Aleph's dashboard, inked for the Moon: one panel docked on the left and ruled in cream ink, the map beside it,
 * square corners, system type, mono labels. The colours are the Tav banner's: night paper, cream ink, a violet river.
 * Violet is the only accent: the main action, what is switched on, progress and focus.
 * Self-contained: this page does not load style.css.
