/*
 * Shared styling for the three hosted pages.
 *
 * Deliberately one small stylesheet with no build step and no dependencies:
 * these pages exist so the App Store, Google Play and a regulator can read
 * them, and the failure mode that matters is "the link is dead", not "the
 * typography is unfashionable". Nothing here loads from a third party — a
 * privacy policy that phones out to a font CDN to render is a bad joke.
 *
 * The palette is the game's: Okabe-Ito accents on the same near-black.
