CSP

Content-Security-Policy	default-src 'self'; style-src 'self' 'unsafe-inline'

The "style-src 'unsafe-inline'" prevents getting +5 points. Inline CSS is used

• for getting 100/100 on Goolge speed test, which does not seem to be possible with external CSS
• to do CSS marking in MediaWiki, e.g. cells in tables
