Thames tweaks
The default blue was not AAA standard against #f8f8f8
so made it darker. Shame to make the vibe less colourful, but accessibility more important. It would be nice to apply the darker blue only when it's on grey background, but that's too much CSS!
Also improve quicksearch results
And fix the contact edit (@nicol I've not tested, but I think the flex-wrap:wrap rule might be needed in core/other themes).
