Text may be better aligned with web redesign text in places. This is just experimentation Re layout, as such not all pages have a background layer.
Why landscape - This would work better on desktop, but smartphones would be able to accommodate too. It allows us to spread things out a bit more and avoid things being scrunched... up as was happening in the portrait version.
The previous version employed E1E1E1 as a background as per apertus CI, but e1e1e1 causes a few problems; It's probably darker than we need and something lighter still works with CI, namely ebebeb. ebebeb is commonplace throughout the Wiki so there's that. Also, when background layers are added to an already overly dark e1e1e1 background e1e1e1 becomes even darker, this was giving the brochure a somewhat depressing feel. See page 04 for ebebeb with a background layer.
To coincide any web page mocks will probably use ebebeb from here-on.
