/* Beture LINE Mini App — design tokens and components.
 *
 * Ported from the Claude Design canvas "Beture LINE Mini App.dc.html". The
 * prototype carried every rule as an inline style; here the same values live as
 * tokens and classes so a colour or radius changes in one place.
 *
 * The prototype also drew a presentation rail and a phone bezel around the app.
 * Inside LINE the Mini App IS the viewport, so that chrome is dev-only and lives
 * behind ?frame=1 (see .dev-* rules at the bottom).
