The style variable is missing in Sphinx 7. Instead, it now uses a list of styles [1]. This new list was already added in Sphinx 5.1. It looks like the style was only removed in Sphinx 7, though.
This commit updates the layout.html template to define the styles variable if it is missing. This makes the change compatible with both Sphinx <5.1 and versions later than that.
This change is enough to make our documentation buildable with Sphinx 7 when using this theme.
