/*
 * MusiX legal pages — shared theme.
 *
 * Palette and gradient are sampled from the app: the four-stop brand gradient
 * (amber → orange → coral → raspberry) defined in MusiXBrand.swift, and the
 * #FC6A45 accent from AccentColor.colorset.
 *
 * The app sets type in BBC Reith Sans, which is a licensed typeface and cannot
 * be redistributed to the web. The stack below names it first so it renders on
 * machines that have it, then falls back to the system UI face — which on iOS
 * and macOS is SF Pro, the closest widely-available neo-grotesque.
