Did a few housekeeping tasks:

• Noted that this "closes" the chapter issue in first comment so that will automatically be closed when this is merged.
• Removed the "todo" config and added to this branch (053eee2)
• Removed the "unedited" flag and added to this branch (053eee2)
• Merged latest main changes into this branch
• Added a stage link with these changes: https://20211117t072414-dot-webalmanac.uk.r.appspot.com/en/2021/css

I've internationalised the links and replaced smart quotes with non-smart quotes in 6171bf4

Added colour swatches:

I want to accept nearly all of the above changes, but there are a few I want to tweak. Should I just make notes of where I want to tweak, accept all, and then make my own changes? I’m not used to this way of managing edits, so assume I don’t know how any of this works (if my question didn’t already make that clear).

[tunetheweb]

If it's a small number of tweaks, then the review feature of GitHub works well.

If it's a larger number of small edits, then I think we've got to trust our authors (but also our editors!). So if @shantsis agrees then I'm happy for you to push straight to this branch for those further tweaks. We can always keep an eye on the commits to see the extra changes.

However, if you are straight out reverting an edit, then it's polite to add a comment using the Review feature of GitHub to highlight your reason for disagreeing with it and why you want to revert it, and then only committing once agreement is reached.

Similarly if you want to make mass changes (e.g. rewrite a whole section, or re-order the whole thing), or other "controversial" changes (and I realise that's a very subjective call!), then a discussion here first would be preferred. Or maybe a follow on PR.

That sound fair to all?

I left comments where appropriate above. Not sure what else I can do at the moment.

Feel free to push it straight in @meyerweb

Doing some minor edits for some issues I've spotted. Then will merge this.

OK completed the final edits.

The main change (other than minor typos and additional code formatting) was to move the charts before the analysis. I appreciate not everyone will agree to this way of presenting the data, but that is the Web Almanac style (present data, then give interpretation) so believe consistency is important here.

I'm going to merge this now but happy to take further PRs if people spot anything!
