/* ============================================================
   AmpUp — shared design tokens & component styles
   Layout concept: dark, high-energy "powered-up" brand shell
   (near-black ground, one voltage-green accent) with bright
   white product/solution cards punched into it like lit screens.
   Committed single dark world — matches the brand exactly as
   briefed, carried consistently across every page.
