   Regola di cascata (Tailwind 4):
   - i default di base stanno in @layer base -> le classi Tailwind
     (text-*, border-*, font-*) continuano a vincere;
   - i componenti (.ub-*, .site-*) sono fuori dai layer -> vincono su
     Tailwind e su ux-improvements.css. Non scrivere qui regole generiche
     su tag (h2, a, div...) fuori da @layer base.
