/**
 * Oystro Design Tokens — "Harness UI" · GLOBAL THEME

 * Canonical direction: OPTION 2 — Modern Infra Cyan (#38BDF8) & Deep Navy.
 * This is the single source of truth for colour, typography, spacing, and
 * shared components across oystro.com, staging, the blog, and docs.
 *
 * Usage (every page <head>):
 *   <link rel="stylesheet" href="/assets/css/tokens.css">
 *
 * Theme flip: set data-theme="light" on <html> (dark is the default).
 * The styleguide (design-system.html) may still preview Option 1 / Option 3 by
 * setting data-option="1" | "3"; production pages omit data-option entirely and
