/* BlueBark v3 — layered hero. Forest atmospheric BG (with center card region masked
 * to cream so no card duplication when the lockup overlays). Clean lockup PNG fg
 * centered. Mission + footer below on solid cream.
 *
 * Asset chain:
 *   /assets/forest-bg-v3.jpg = composite source with card region cream-filled (#f5f4ee)
 *                              and feathered seam — only forest+circuit edges remain
 *                              visually; card region matches body+lockup substrate
 *                              for seamless layering.
 *   /assets/lockup-hero-v5.png = clean lockup card (wordmark + tree + tagline) on
 *                                cream substrate, drawn ON TOP of the forest bg.
 *                                Sits exactly where the original card region was =
 *                                forest stays on edges, lockup carries identity.
