/*
  Smart ITC — site, account and admin styles.
  The look is carried over from the old site (old/Smartitc.ir/css/style.css): light grey page, teal #079992 and
  navy #0c2461, 42px "glass" cards with a white border and soft shadow, the line.png heading underline, blurred
  blue blobs, and the portfolio cards with the curved white label. Animations are added on top; all of them
  switch off for prefers-reduced-motion.
