"""A standalone app's paths are the folders its code opens below data_root.
|
|
|
|
The site prints data_root joined to each entry's standalone destination, so a
|
|
frontend's layout written there (Batocera's bios/switch/) sends the reader to a
|
|
folder the app never reads. A frontend folder name is allowed only where the
|
|
app's own code joins that folder to its data root.
