/* TPay web app.
 *
 * Ported from the ACCEPTED design: website/mockups/tpay-57.6/index.html (16 Sep 2026).
 * The previous stylesheet was a light, cream-coloured store; the accepted TPay identity is
 * the dark navy/violet field with the gold gradient wordmark, so that is what ships.
 *
 * Mobile-first. The accepted design is a single 460px column, which is already the phone
 * layout; desktop keeps that column centred rather than stretching cards to full width.
