/**
 * @rpg/engine v2 — воксельный движок (скелет).
 *
 * Принципы (docs/plan.md, «Направление v2» и «Уроки черновика»):
 * - three.js — только низкоуровневый рендер-бэкенд; ядро движка о нём не знает.
 * - Все позиции/направления — в одном мировом пространстве; проекция/рендер —
 *   единственная точка преобразования на границе (урок v1 «летающих» объектов).
 * - Чистая математика — отдельно от вьюх, тестируется без рендера.
 * - Агентный мост и CLI-проверки — часть ядра, а не надстройка.
 *
 * Модули (появятся по мере треков v2): мир/чанки, модели (JSON + .vox),
 * рига/анимация (кривые), генераторы моделей, агентный мост.
