/**
 * Worldview category listing — the browse entry points.
 *
 * Exposes the two top-level trees of the worldview domain:
 *   - PRTS archive categories (collection/document/media/...) and their
 *     first-level groups (the unit a player opens to read documents)
 *   - In-game wiki categories and the groups under each
 *
 * Both trees are eager-loaded and cached in `worldviewCore`; this module
 * just shapes them for tool consumption (resolving display names through
 * i18n). Depends on `./worldviewCore.js` for the catalog loaders and
 * `./texts.js` for name resolution.
