  background: linear-gradient(180deg, 
    #ffffff 0%,     /* Pure white */
    #f0f4ff 50%,    /* Light blue */

    #f0f4ff 50%,    /* Blue-purple mix - tech-forward */
    #faf5ff 100%    /* Light purple tint - cohesive */
  );
}

.download-container {
  background: linear-gradient(180deg, 
    #ffffff 0%, 
    #fefaff 50%,    /* Very subtle purple tint */
    #ffffff 100%
  );
  box-shadow: 
    0 25px 80px rgba(99, 102, 241, 0.15),  /* Brand-colored shadow */
