/* ============================================================================
   MAFFEI LABS — WOW LAYER (FASE A "Stella Viva")
   ----------------------------------------------------------------------------
   Layer additivo on-top di style.css. NON modifica logo né colori (--accent,
   --accent-bright, --accent-glow rimangono identici). Aggiunge motion cinematico,
   sparkles, halo, letter-rise, hover lift, skeleton constellation, page
   transitions.

   Aderente a `prefers-reduced-motion`: tutti gli effetti disabilitati lì sotto.
