/**
 * Unit tests for the per-site navigation configuration (task 04).
 *
 * `NAV_CONFIG` + helpers are pure (no solid-js / router / meta imports), so
 * these mirror the acceptance matrix directly. Integration / visual checks
 * (rendering on `nessa.localhost:3000`) are covered by the build gate and
 * manual validation described in the task; here we assert the data layer.
