/*
 * Dateien - monochrome.
 *
 * Structure is inherited from GRATICULE (sharp corners, hairlines instead of
 * borders, no shadows, Archivo + JetBrains Mono, the app's own scrollbar), but
 * the palette is pure greyscale: there is no hue anywhere. Emphasis is carried
 * by luminance alone, which means the scale has to do all the work - hence the
 * deliberate gaps between --text-muted, --text-secondary and --text-primary.
 *
 * White is the accent. It is expensive, so it is spent only on the active nav
 * item, the primary button and focus rings.
