   AURORA POZADÍ (za Hub) – měkké atmosférické světlo, aby měl frosted glass
   co „zmrazit". Fixní vrstva přes celý viewport, POD obsahem Hubu: z-index:-1
   uvnitř stacking kontextu #app → leží nad (průhledným) #app pozadím, ale za
   headerem, navigací i obsahem Hubu. Statická (minimalismus – žádné výrazné
   efekty ani pohyb), plně respektuje světlý motiv. Renderuje ji renderHub()
   jako 1. potomka #appMain; při přepnutí tabu se sama uklidí (innerHTML swap).
