   AISensus design system (see DESIGN.md)
   Direction: One motif. The quarter-circle from the AISensus mark (a sensor's
   ripple) is the only shape: tabs, buttons, frames, tiles, the hero, the footer.
   One face: Rubik. Ground swaps by chapter; ink stays near-black; safety orange
   is the action and the motif.
