+// features/admin/index.js — the whole Admin area as one feature module.
+//
+// Admin owns every /admin* sub-route: /admin & /admin/dashboard (overview
+// board), /admin/config/<cat> (config-form pages), /admin/system[/<sub>]
+// (system ops boards), /admin/tools/ssh-access, /admin/tools/peers. The router
+// re-runs mount() on each distinct /admin* path; mount() just parses the
+// category and hands it to window.configManager.renderConfig(), which owns the
+// overview/ssh/peers/system/config-form dispatch and lazy-loads the per-category
+// sub-controllers. configManager is a system-loader singleton — call
+// renderConfig(), never `new`. (The legacy /config, /ssh, /peers redirect
+// handlers stay as-is; they just bounce into /admin/* which this feature serves.)
