/* Tokens for the 4ward guidance holding page.
 *
 * Not new tokens. Every value is lifted from the product system
 * (src/app/globals.css, brand brief section 4) so the holding page and the site
 * that replaces it are one brand. Hex is kept as hex on purpose: the brief's
 * contrast ratios were measured from these exact values.
 *
 * Standalone by design: nginx serves this with no build step behind it, so it
 * imports nothing from src/. Dark follows the operating system, because a
 * static page with no script has no toggle to set a class from.
