/*
 * Guide Gate — shared popup overlay for /guide/ and /sourcing-guide/
 *
 * Activated by /assets/guide-gate.js when no confirmed-token is found
 * in localStorage. Blurs the guide content underneath, locks scroll,
 * and asks for email. Dismisses itself after Acumbamail confirmation
 * round-trip (?confirmed=1 in URL).
 *
 * Uses the same design tokens as the host page (set on :root in each
 * guide's <style>), so theme toggle (dark/light) propagates here.
