/* Compliance Central — phone scanner.
 *
 * Held one-handed, at arm's length, in showroom glare, by someone who is also
 * holding a customer's licence. Every choice below answers to that: the single
 * primary action is gold (the only thing on a navy page that survives direct
 * sunlight), targets are finger-sized, and nothing that matters sits in the
 * band along the bottom edge where a thumb and the browser's own chrome live.
 *
 * Tokens are the same brand set the site and the side panel use, so the three
 * surfaces read as one product. This page's surfaces are the dark end of that
 * palette; the site is the light end. The three faces are the extension's own,
 * self-hosted from docs/fonts so the phone never falls back to whatever the
 * OS ships — the page's CSP allows fonts from this origin only.
