/**
 * Navigation — autonomiczna, error-proof warstwa routingu.
 *
 * Zasady:
 *  - Unknown dashboard → render `not-found`, NIE crash
 *  - Unauthorized → `access-denied` z CTA, NIE redirect do `/`
 *  - Unknown params → ignore, NIE throw
 *  - State w URL deserializowany odporny na nieznane klucze
 *
 * Router adapter, nie hard dep na @angular/router — framework może żyć
 * w shellu hostującym (np. dashboard wbudowany w portal).
