/* Codemart — codeartistry.co
   Design: confident, high-contrast dispatch-console aesthetic on a
   black / NVIDIA-green (#76B900) / white palette. Flat surfaces,
   pill CTAs, tabular numerals for the real demo phone number.
   Green text is only ever placed on black (8:1+); on white/paper
   surfaces green is reserved for icons, borders and pill chips using
   a darkened AA-safe shade, never for body text. */
