Feature Cards.

---
/**
 * FeatureCards: features as a joined index grid. Cells share hairlines like a
 * spec sheet, each with a number, an optional tag, a display-face title and
 * an optional link. Hover tints the cell.
 *
 * @example
 * <FeatureCards title="Six habits that" accent="make gear last." items={[
 *   { title: "Repairs for life", body: "Send any pack back.", tag: "Service", href: "/repairs" },
 * ]} />
