+> The imported `file`s (which have a certain file extension (`ico`, `png`)) (Node.js) modules) copy the files themselves into the `static` folder when the modules are loaded. In module relading mode they remove them if they are not imported anymore.
+
+> The `default` `export` of (Node.js) `module`s (which have a certain file extension (`js`, `json`, `html`) in their base file name) are written as the contents of the output files (into the `static` folder). The full file names of the output files are the base file names of the (Node.js) `module`s.
