/* nimu — shared landing shell (Traced). Locked design system:
 * Bricolage + Outfit + Geist Mono, warm near-black, signal-green, node-kind
 * colours, warm grain, faithful .rf-node/.rf-edge-label canvas vocabulary,
 * and the section flow animations. Pages link this file. */

/* ==================================================================
 *  nimu · landing — evolved from "Spotlight Dark", 3 alternatives that
 *  read as OURS, not a Linear clone. Same layout throughout.
 *
 *  Shared nimu DNA (all three): Bricolage display + Outfit body (not
 *  Inter), warm paper grain, the brand route mark, warm near-black,
 *  signal-green, and the node-kind colour family.
 *
 *  D  TRACED      — the route threads the page: numbered "stops",
 *                   hand-drawn trace dividers, a trace into the hero.
 *  E  KIND SYSTEM — the 5 node-kind colours become the accent system;
 *                   the hero flow is mid-PLAY (a lit path travels).
 *  F  WARM EDITORIAL — oversized display + big ghost numerals, heavier
 *                   grain, generous, magazine-like.
