   The sidebar version of .ai-sb-credits-ring assumes a dark navy
   background and uses white-on-white-alpha tokens for the track + label
   text. On the Dashboard, the KPI card surface flips with the theme so
   we need EXPLICIT colors per mode — token fallbacks (--ai-ink etc.)
   don't help because they're shared between modes and end up matching
   the surrounding card (invisible) in one of them.

   Light mode: ring track is a soft navy alpha, label text is the same
   dark navy used elsewhere on the card.
   Dark mode: ring track is white alpha, label text is pure white. */
