 * landing.css — Public landing page (Phase 2.B.2.combo.7)
 *
 * Standalone stylesheet loaded ONLY on the / landing page. Reuses the
 * Khand + Montserrat fonts from style.css but defines its own warm-
 * neutral, gray-leaning palette so the landing page can evolve
 * independently of the internal Truth Engine pages.
 *
 * Design principles:
 *   • Gray-leaning warm neutrals (NOT pink, NOT salmon, NOT beige)
 *   • TML orange #B64926 used sparingly for CTAs / accents only
 *   • All 8 zone cards equal height (min-height 280px)
 *   • Subtle, slow animations (8s breathing pulse on hero sunburst)
 *   • Cards visibly lift from page bg via shadow + border + tinted fill
 * ────────────────────────────────────────────────────────────────────── */
