[template] Dark mode

[xfq]

Is there an interest in implementing dark mode for the charter template?

I have a semi-finished example here for your reference: https://xfq.github.io/testing/dap-charter-dark-mode/DASCharter-2020.html

The preview looks okay and I think this is a nice thing to do. @xfq what items remain to be finished?

Two things that I currently think of:

• The W3C logo is too bright. We should consider replacing it with white text on a blue background.
• The contrast of the Timeline table and the testing policy (in § 3 Success Criteria) is too low and needs to be adjusted.

Waiting for @xfq to finish the proposed dark mode stylesheet before the template is updated.
