/**
 * UpPay site footer — canonical shared chrome (donate-test).
 * #uppay-footer-root reserves shell space before js/uppay-local-footer.js mounts.
 *
 * SHARED CHROME CONTRACT
 * This file is the ONLY source of truth for footer geometry and visuals.
 * Every rule is scoped under #uppay-site-footer so page stylesheets using
 * class-only selectors (including the games bundle's legacy footer copy)
 * can never win regardless of <link> order.
 * Pages may not style descendants of #uppay-site-footer.
 *
 * Requires css/uppay-design-tokens.css first.
