/* ─────────────────────────────────────────────────────────────────────────────
   AgentGate — design system ("Checkpoint")

   Principles
   1. Colour means a verdict. The interface is ink and paper; the only saturated
      colours are the four verdicts — allow, redact, review, block — and they are
      never used decoratively for anything else.
   2. Evidence looks like evidence: monospace for anything a machine produced
      (hashes, rule ids, timings), a serif italic for the human voice.
   3. Hairlines over boxes, type over ornament.

   Structure:  tokens → base → layout → navigation → components → patterns →
               legacy aliases (dashboard, docs, admin) → utilities → print
