/**
 * Ingefy Design System — Core Tokens
 * ====================================
 *
 * Visual direction: Fiscal.ai / Koyfin / Bloomberg terminal
 * Principle: density is a feature, dark is default, accent ≠ bull
 *
 * ADDING A NEW TOKEN
 * ------------------
 * 1. Add to :root (light value)
 * 2. Add to .dark (dark value)
 * 3. Use via var(--token-name) — NEVER hardcode hex in component files
 *
 * KEY DISTINCTIONS
 * ----------------
 * --color-accent  = deep editorial green (UI chrome, branding, CTAs)
 * --color-bull    = vivid financial green (positive price movements, gains)
 * These are intentionally different. A CTA must not look like a ticker in the green.
 *
 * CONVENTION: NO HARDCODED HEX IN COMPONENTS
 * -------------------------------------------
 * WRONG:  color: #1F4E3D;
 * RIGHT:  color: var(--color-accent);
 * Verify: grep -rn "#[0-9a-fA-F]\{6\}" public/ (should only hit this file)
