+/* UrlList — inert, copy-only rendering of URLs extracted from a reported
+ * phishing/spam email (REVIEW-03, D-09).
+ *
+ * D-09 is a deliberately STRICTER-than-sanitization posture: extracted URLs
+ * are attacker-controlled content and must never be rendered as anything
+ * clickable. There is no anchor tag with a navigation attribute, no
+ * `<Link>`, and no navigating `onClick` anywhere in this file — the only
+ * affordance is copy-to-clipboard via an icon-only button. Do not "improve"
+ * this by adding a real link. */
