In ndcode_site:

* Add blog post about refactoring, with refactoring image and render source
* Simplify navbar with .extend-background class so we can use only one container

* Consistency changes wrt nick_site, makes page footer slightly taller

In zettair:
* Fix problem of HTML entities not appearing in website search results
