 * MENU REGISTRY — sursa unica de adevar pentru Main Navigator (14 sectiuni).

 * releaseStage si (la sectiuni) children. Sidebar-ul si ruta catch-all pentru

 * status vs releaseStage sunt lucruri diferite si nu se confunda:
 *   releaseStage = CAND e planificat sa existe (mvp / a3 / a4)
 *   status       = daca exista ACUM in cod ('ready') sau nu ('planned')
