- Hide sidebar in pages visible in the top nav, except for Docs
- Create an "About" page, featuring the design principles
- Update components illustration
- Move the "What's new in Flamenco 3" page in the FAQ
- Add TOD to the FAQ
- Tweak homepage layout to use two columns
- Styling: slightly reduce max page width (around 12 words per line)
- Styling: tweak padding for titles and paragraphs
Remove the "what is new" link, because it's not that relevant for a quick-
start page. Also it got lost a bit between the videos and felt out of
place.
