/**
 * Cyber Canvas Theme - Dark Mode Structural Styles
 *
 * NOTE: All colour custom properties (--cc-bg-primary, --cc-link-color,
 * --cc-btn-bg, etc.) are output dynamically by inc/dark-mode/engine.php
 * based on the admin colour settings.  Do NOT define colour tokens here —
 * they will override the dynamic output and break palette customisation.
 *
 * This file is kept for any light/dark structural helpers that are not
 * colour values (e.g. transition, opacity, shadow shape tokens).
