/* SAILab, Siena Artificial Intelligence Lab.
   Palette from Siena's coat of arms (the Balzana, white over black) and one accent,
   terra di Siena bruciata: the burnt sienna pigment is named after the city's earth.
   Bodoni Moda (Italian, high contrast like the Duomo's marble bands) for headings,
   Hanken Grotesk for reading. A fixed light/black split is the identity itself, so
   there is no theme toggle: both halves of the Balzana are always on screen. */
