/**
 * Cookie consent banner + consent-gated RB2B loader for docs.lancedb.com.
 *
 * Mintlify loads every .js file in the content directory on every page, so this
 * file runs site-wide. RB2B is opt-in: its script is never requested until the
 * visitor clicks "Accept". The choice is stored in localStorage and can be
 * changed later from the "Cookie settings" footer link (any link to
 * #cookie-settings) or window.lancedbCookieConsent.open().
 *
 * GA4 and Mintlify's own analytics are NOT gated by this banner.
