/* ===== Design tokens — sourced from the Integrivex mark (navy → electric blue) =====
   Light surface: the mark was designed for a white ground, so this is closer to its
   native habitat than the dark variant was. Text tokens are chosen to clear WCAG AA
   against --bg; --blue-400 is kept for decorative use only (particles, glows, rings)
   since it doesn't have enough contrast on white to carry small text. */
