New Website changes available for preview here

Thanks @OchiengPaul442 , how does one navigate to this page? Can we be able to make the entire website's landing page point to this maintenance page by just making a small change in the website code? Or just deploying it separately as an App Engine instance and just redirecting traffic to this page whenever one accesses airqo.net? cc: @Psalmz777

Hi @OchiengPaul442 , I hope this finds you well.
Just sharing a brief note about this PR (subject) below....

So we recently had a meeting with @Psalmz777 where we agreed to have a new folder in our frontend project where we shall create a SINGLE file frontend project without any framework --- just simple plain HTML one page which we shall deploy to App Engine SEPARATELY.

WHY THIS DIRECTION?

• We did realise that some of the challenges with using frameworks is the reason we are even creating a maintenance page.
• We do not want to reach a level where we also need to create a maintenance page for a maintenance page! :)
• Lastly, we need to be able to ensure that our maintenance will always be readily available regardless of any circumstances. One of the ways for this is to ensure that it does not have dependencies on any framework (Django, etc) or DB technology. Just simple plain HTML + Javascript code in a "single file" project should be enough.
