+"""Logging setup.
+
+The rest of the code gets the logger through this module rather than
+``logging.getLogger`` to make sure that it is configured.
+
+Logging levels are used for specific purposes:
+
+- errors are used in ``LOGGER`` for unreachable or unusable external resources,
+  including unreachable stylesheets, unreachables images and unreadable images;
+- warnings are used in ``LOGGER`` for unknown or bad HTML/CSS syntaxes,
+  unreachable local fonts and various non-fatal problems;
+- infos are used in ``PROCESS_LOGGER`` to advertise rendering steps.
