+/* MoreDrawer — phase 02 (DRAWER-01..05).
+ *
+ * shadcn Sheet (side="right") with three top-to-bottom sections:
+ *   1. Mobile sections — Engagement (in-shell route, no ExternalLink hint)
+ *   2. Full site       — desktop-only routes, each with ExternalLink hint
+ *   3. Account         — current user (read-only) + Sign out
+ *
+ * Open state is controlled by the parent so the header avatar AND the
+ * bottom-nav More cell can both trigger this single drawer. */
