+- A server-rendered web control panel for discovering and running reviewed,

+- Per-group task queues, SQLite run history, captured output, and task-process
+  cancellation.
+- The default command starts the control panel with `python -m app`.

 Intended use:
 
-- Run small helper scripts mounted at runtime, for example media metadata
-  extraction scripts used by local AI tools.
+- Run reviewed, autonomous task scripts mounted at runtime, including metadata
+  extraction scripts that need ExifTool.
+- Use the included task control panel. Its generic deployment example and
+  application documentation are in `python-tools/`.
 - Keep host systems clean by avoiding host-level package installs.
