+ *  - Which names are shown in usage / error messages
+ *
+ * Both DE and EN subcommand names are always recognised, so admins can
+ * switch languages without breaking muscle memory mid-session.

+ * TeamGUI – two-layer navigation with optional pagination on rank pages.
+ *
+ *  Layer 1  Overview  – one configurable icon per rank.
+ *                       Slot read from rank-settings.<rank>.slot (config.yml).
+ *                       Clicking opens the rank's member page.
+ *
+ *  Layer 2  Rank Page – shows player heads.
+ *                       If members exceed capacity → pagination.
+ *                       Footer layout (slots 45-53):
+ *                         45  ← prev rank  (wraps)
+ *                         46  ← prev page  (hidden if page 0)
+ *                         49     home
+ *                         52  → next page  (hidden if last page)
+ *                         53  → next rank  (wraps)
+ *
+ * Page capacity:
+ *   rank-settings.<rank>.member_slots defined → capacity = list size
+ *   otherwise                                 → gui.members_per_page (default 40)
+ *
+ * GUI size is always 54 and NOT configurable.
