   UTB AURUM — shared design system
   University of Tampa Bay · 4i Industry Integrated Innovation Institution
   Gold-leaf on porcelain: white + champagne surfaces, gilt accents,
   espresso ink. One source of truth for every page: tokens, base,
   nav, footer, buttons, type, scroll-reveal, and the depth system.
   NOTE: legacy token names (--void/--abyss/--star/--moon/--cyan/
   --indigo/--violet/--spectral…) are kept so page-level styles keep
   working — their VALUES now resolve to the light gold system:
   "dark band" tokens are champagne surfaces, "ink on dark" tokens
   are espresso inks, and the spectral ramp is champagne→gilt→amber.
