/* IC portal styling.
 *
 * Same token vocabulary as the proponent widget (docservice/widget/styles.css)
 * so the two surfaces of the same product read as one. No external font: a
 * strict-CSP bank portal makes no network requests it does not have to, so this
 * uses the platform's own UI stack. Colour, spacing and rhythm are ours. */
