   ARKAN ONE Design Integration 2.0 — canonical motion vocabulary
   Ported from claude_code_handoff/tokens/arkan-tokens.css. Purely
   additive — nothing above this block is touched or removed here.
   Every animation explains an event; the ONLY infinite one is
   `.ark-skeleton`'s shimmer, and only while loading. Everything
   above this line that pulses/drifts permanently (aurora blobs,
   .status-dot--live/--warning/--error, .page-loading-bar's
   gradient-shift) is a real, separate design-fidelity finding —
   flagged for Phase I (motion + accessibility), not fixed here.
