   Aeldorado — Billing Page (Liquid Glass, Perf-first)
   
   Matches dashboard's liquid-glass design system exactly.
   Performance strategy (same as dashboard):
   • backdrop-filter only on ::before pseudo — isolates blur
   • Animate ONLY opacity + transform — compositor thread only
   • No box-shadow animation — causes layout reflow
   • No heavy filters or backdrop-filter on hover
   • will-change only on interaction, not globally
