/* ═══════════════════════════════════════════════════════════════════════════
   LABELSETS DESIGN SYSTEM v2 — institutional dark
   ─────────────────────────────────────────────────────────────────────────
   Palette inspired by the FTX Claims Portal + procurement-grade finance UIs
   (Bloomberg Terminal, Kraken Pro, BitGo). Warmer-than-black canvas, muted
   institutional teal for CTAs, bright cyan for highlights.

   Every procurement-facing page should use these tokens rather than inline
   values. Changing the accent here cascades site-wide.
