/*
  Kinetiq Elysium explorer token layer (style reference only, no copied assets).
  Colors follow the explorer's warm neutral and teal brand scales, light and dark.
  Deviations for WCAG AA: --ink-3 warm-600 (explorer zinc-400 is 2.45:1), --ok positive-700,
  --stop negative-800 text with --stop-mark negative-600, --warn-soft tints, a solid testnet chip
  with warm-950 ink, dark --border brand-600 so dividers stay visible on --surface-2.
  Type uses the local system sans and mono stacks only. The explorer's DM Sans is not
  self-hosted and no network fonts load, so glyph shapes differ from the explorer.
