/* ── Landing v14 (illustrated airport) — issue #228 ───────────────
 *
 * Five sections (.lp-hero → .lp-why → .lp-mechanics → .lp-roles →
 * .lp-checkpoint) ported from .local/landing-rewrite-v14.html with
 * layout fixes:
 *   - hero callouts evenly distributed, no overlaps, none touching
 *     the card edge; mobile collapses to a stacked .lp-callout-strip
 *   - tower visually anchored to the bottom of its container with a
 *     subtle ground glow; CSS-only sticky on desktop, static on mobile
 *   - mechanics: six .step-NN cards along the runway diagonal from
 *     bottom-left to top-right, percent-anchored
 *   - roles: six role cards positioned by visual metaphor over the
 *     apron scene; not a bottom strip on desktop
 *   - checkpoint: checklist sits beside the visual on desktop, stacks
 *     under it on mobile
 *
 * All landing classes are prefixed `.lp-` (or use the contract names
 * called out in the ticket: .mechanics-step, .step-NN, .role-card,
 * .role-pilot, .tower-visual-wrap, etc.) so the new styles don't
 * stomp on dashboard, receipt, or legal pages that share Layout. */
