/* ============================================================
   CODE & CHAOS — BRAND SYSTEM v2.1 "ONYX & METAL"
   Source of truth: Vault/Code and Chaos Brand/ (BRAND.md + Application System sheet)
   Structure meets instinct. Precision creates impact. Order powers chaos.

   Palette: Onyx #0B0B0D · Bone #E7E1D7 · Crimson #8F1F28 · Graphite #3A3A40
            + Silver (structure) · Gold (premium highlights)
   Hierarchy law (from the sheet): typography leads · circuitry as structure,
   not clutter · crimson for emphasis, never a base field · gold and silver
   never mixed without hierarchy (silver = structural, gold = importance).

   Type (per Application System): Bodoni Moda (wordmark/hero) ·
   DM Serif Display (headings) · Cormorant Garamond (editorial/italic) ·
   Manrope (body & interface) · IBM Plex Mono (data/receipts)
