 * Arrow Phase 30 — the visual system.
 *
 * Loaded last, so it is the layer that decides how Arrow feels. The brand
 * is unchanged: near-black, mint, the pixel arrow, the same type. What
 * changes is craft — real elevation instead of flat bordered boxes, one
 * spacing scale instead of ad-hoc margins, motion that means something, and
 * cards built around the picture rather than around a table of figures.
 *
 * Rules kept from the rest of the site: no remote fonts or images (the CSP
 * forbids them), every number still comes from the chain, and everything
 * here respects prefers-reduced-motion.
