/* Signer-portal design tokens.
 *
 * One declaration per line, on purpose: test/portal-contrast.test.js parses this
 * file with a `--token: value;` regex and measures the pairs. styles.css carries
 * no colour literals, so this file is the only place a colour can enter the
 * portal -- which is what makes "every colour is measured" a checkable claim
 * rather than an intention.
 *
 * Light only. `color-scheme: light` is declared below and nothing in the
 * mobile-web qualification requires a dark ceremony; adding one doubles the
 * pairs that must be proven, so it is a deliberate V1 omission, not an oversight.
