/* === Lead-magnet Guide Page (canonical) ===
 * Wave 11a (NEW-3 Path B). Lifted from packages/site-hub/src/css/guide.css.
 * Designed to render correctly on hub (vanilla CSS theme with --green / --ink /
 * --cream / --space-* tokens) AND on the 5 Tailwind product sites that ship
 * with their own design tokens. The :root fallback block below provides
 * sensible defaults for every var the rules reference, so a Tailwind site
 * that imports this file standalone gets a usable result without having to
 * define all the hub design tokens.
 *
 * Per-site sites that DO define matching tokens (hub) override the fallbacks
 * via cascade — their :root tokens win because their <link> ships first.
 */

:root {
    /* Color fallbacks — only applied if the consuming site doesn't already
     * define these tokens. Hub overrides via its design system; product sites
     * pick up these values verbatim. */
