 * Centered single column, max-w-5xl (64rem) container, min-height 60vh.
 * Background: dot pattern + warm linear overlay. Cards: md shadow, xl radius.
 * Heading: 7xl, weight 400, -0.04em tracking, right aligned. Subheading: lg.
 * Entrance: flip-up 700ms, 0ms stagger. Scroll: fade-on-scroll (driven by the
 * --amber-feat-sc20-fade variable the scoped script sets).
 * Mobile: stack · Tablet: single column · Desktop: three-column icon grid.
 *
 * Every colour, space, radius, shadow and duration comes from
 * assets/css/design-tokens.css so the band follows the design system and
 * stays readable under [data-theme="dark"].
