/*
 * Next Commerce — Colors & Type (consolidated)
 *
 * This file bundles the four token files in tokens/ into a single drop-in stylesheet.
 * Load this ONCE in an HTML artifact and you get the full docs-channel design language:
 *   - Brand + semantic color scales
 *   - Layout, radius, shadow, spacing tokens
 *   - Dark mode (default) + Light mode (via [data-theme="light"])
 *   - Typography stacks and scale
 *   - Semantic element styles for prose (h1-h6, p, code, small, etc.)
 *
 * Loads Inter + JetBrains Mono from Google Fonts.
 * For production, prefer per-repo font loading (next/font/google, etc.).
