/* Bud Decision Studio product page.
 * The page is a dark ink ground tinted toward Bud violet (the app icon's ground). Bud's three logo violets are the
 * only data colors; amber means "ask a human" and green "act automatically", as in the app. The replay of the app in
 * the hero uses the app's own light theme tokens (DESIGN.md), so it reads as the real product on a lit screen. */
