/*
 * Sanrad Payments -- mobile-first stylesheet.
 *
 * Built for one-handed phone use first: a fixed bottom nav within thumb
 * reach, 16px minimum input text (anything smaller makes iOS Safari zoom on
 * focus), and 44px minimum tap targets. The desktop layout is a widening of
 * the same structure, not a separate design.
 *
 * Brand blue #5b9bd5 is sampled from the supplied logo.
