   CONNECTRA "Campfire for human connection" theme: the ONLY place colours, fonts, spacing and
   motion are defined. Every page loads this file first; page stylesheets only lay things out
   using these tokens. Slate night by default, a warm light variant, one amber accent, and a
   flame gradient reserved for special moments (match found, connected, a win, the flame mark).
   Token names are historical: "ember" = Primary, "glow" = Warning/streaks, "mint" = Success,
   "rose" = Error, "sky" = Info.
