/**
 * Moom Core CSS — Design System Bridge
 *
 * Source of truth: moom-brand.css (design system mode)
 * This file bridges legacy token names (--moom-green, --font-body) to
 * design system tokens (--accent-camel, --font-base) so existing viewers
 * continue working while new/rebuilt viewers use standard tokens directly.
 *
 * Migration: viewers being rebuilt should use --accent-camel, --font-base, etc.
 * Legacy: --moom-green, --font-body still resolve correctly via aliases below.
