   Cosmic Cadets — theme
   Deep-space dark UI, glassy cards, neon glow accents.
   Design tokens live in css/tokens.css (source of truth).
   The :root block below is a BRIDGE: it maps this file's
   legacy var names onto the Cosmic Cadets tokens, so existing
   usages recolor without a sweeping rename. New code should
   reference the --color-* / --glow-* / --space-* tokens directly.
