/* ============================================================
   Haoying Export Site — design system v3 (client brand VI, gold)
   Source: official LOGO color sampling + VI manual p.6 gold gradient
   sample (client-provided, 2026-10-13). Replaces the Phase 2 steel-blue
   scheme, which is DEPRECATED.
   - Brand gold #E5AD12 fills primary CTAs with DARK text (--color-on-accent).
   - White-background links/eyebrows use text-safe gold #8A5A00 (--color-accent-text).
   - Gold text on dark surfaces uses --color-accent-strong #F2BC14.
   - Warm charcoal neutrals derived from the LOGO wordmark #474747.
   - Gold discipline: brand color for primary CTA / Series tags / active
     states / key highlights ONLY — never for promotional urgency styling.
   - Legacy variable names (--accent, --border, --ink …) remain as ALIASES.
   - Fonts: Inter (display/body) + JetBrains Mono (series codes, specs).
     Declared as local-first stacks — no external font/CDN requests.
