 * Same-origin and nothing else: no CDN, no web font, no analytics tag. A

 * and something the policy would then have to disclose.
 *
 * Colours mirror the app's palette (mobile/src/assets/tailwind.css): amber
 * #f5c518 on near-black in dark mode, which is what the app actually looks
 * like. Light mode is the default because that is what a store reviewer's
 * desktop browser is usually in. */
