/*
 * Mission Broadcast docs — landing-page styles (MB-145, Pass 6).
 *
 * Implements design-spec.md §5 (search-centric landing): warm-paper hero with a
 * prominent search box, color-coded role cards (parent=navy / missionary=sage /
 * subscriber=coral), a common-tasks index on a sage-tint band, and the
 * "how the pieces fit" explainer. Matches landing-mockup.html (light) and
 * landing-mockup-dark.html (dark).
 *
 * All styling is scoped to `.mb-home` (the wrapper in index.md) so it never
 * touches content pages. Palette tokens come from extra.css (--lp-*).
 * No inline styles — CSP-readiness rule.
