/* ==========================================================================
   E-commerce Nexus — tema «default»
   Base neutra, colori standard: è il tema che si clona per un negozio nuovo.
   I temi di lusso stanno in una cartella sorella (core/theme/<nome>/) e
   cambiano estetica, non rotte né dati.

   Nessun colore nel markup: tutto passa dai token qui sotto, e il brand li
   sovrascrive da config/instance.php (tema.accento, tema.raggio).
