This is a tracker issue for the updates to be made following the merge of the main PR addressing #193:

• [x] Prep: #243
• [x] Two reviews and final merge of #229
• [x] #245
• [x] #246
• [x] #248
• [x] #256
• [x] #257
• [x] Consolidate /images and /docs/images - #250
• [x] Rename the label “Docs Assessment” … probably manually first (so as to keep the tagged items), and then updating the settings file
• [ ] More copyedit passes forthcoming ...

for Rename the label “Docs Assessment”, I think we can do it this way:

1. add the new label to the settings file
2. search for all existing "Docs Assessment" issues/PRs 2.1. add the new label
3. remove old label from settings file

There will be a step there where all the relevant issues/PRs have 2 labels, but I think this'll be the cleanest path with the least work
