+"""sglang-omni backend — setup wizard, server specs, model management.
+
+A package of focused modules behind one import surface: everything public
+is re-exported here, so callers (the hub, the CLI, tests) keep using
+``backends.sglomni.<name>`` regardless of which module implements it.
+
+Modules:
+    constants   shared constants (package name, port, timeouts, configs)
+    catalog     the model catalog + the install tree shape
+    gpu         the NVIDIA GPU facts (nvidia-smi) launch decisions use
+    pythonenv   interpreter selection/provisioning for the backend venv
+    models      model install state, (un)install, run-model resolution
+    status      detect() for the hub's backend menu + the server spec
+    wizard      the TUI wizard, configure screen, uninstall/update, CLI
