+Base image:
+
+- `python:3` for the `:3` and `:latest` tags.
+- `python:3.13` for the `:3.13` tag.
+- Minor and patch releases are picked up when each image is rebuilt.
+
+Installed from Debian apt repositories:
+
+- `ca-certificates`
+- `exiftool`

+Intended use:
+
+- Run small helper scripts mounted at runtime, for example media metadata
+  extraction scripts used by local AI tools.
+- Keep host systems clean by avoiding host-level package installs.
