/**
 * v1.25.11 (#148) — the shared Appearance group registry.
 *
 * `layout-groups` is the single source of truth consumed by BOTH the client
 * hub (`layout-section.tsx`) and the server subpage route
 * (`app/settings/layout/[module]/page.tsx`, via `LAYOUT_GROUP_IDS` in
 * `generateStaticParams()`). These tests pin the param → section mapping: the
 * id list (the statically-generated subpage params), the guard, the per-module
 * gate expectations, and that each group resolves a distinct section body.
