/*
 * Kalozi public site.
 *
 * Deliberately one small stylesheet with no build step and no dependencies: these pages
 * exist so that store reviewers and users find working links, and the worst possible
 * failure mode is a legal page that 500s because a framework upgrade broke. Plain HTML
 * and CSS cannot break.
 *
 * Colours mirror src/theme/tokens.js. They are duplicated rather than imported because
 * this site deploys independently of the app — a shared build step would couple a store
 * blocker to the mobile toolchain.
