+/* ═══════════════════════════════════════════════════════════════════════
+   The Radical Party — shared footer / wayfinding component.
+
+   ONE script, loaded on every subdomain, so no island is a dead end:
+       <script src="https://theradicalparty.com/footer.js" defer></script>
+
+   - Self-contained: injects itself into <body>, styles live in a Shadow DOM
+     so nothing leaks in or out of the host page's CSS.
+   - Central: edit this one file, every site updates. No per-repo redeploy.
+   - Two modes, chosen via a data attribute on the script tag:
+       (default)            full footer bar at the end of the page.
+       data-mode="pill"     compact fixed corner badge — for full-screen apps
+                            (maps, games) where a block footer would be hidden.
+     Optional: data-accent="#ff0099" to match a site's own accent.
