Pull review checklist

Unless otherwise noted above, this PR will be considered ready for review when all four items have been checked.

• [X ] All changes to text follow "one sentence per line" [Manubot instructions]
• [ X] All citations follow the Manubot citation instructions
• [X ] All changes or additions to tables follow the Manubot table instructions
• [X ] All figures follow the Manubot figure instructions
• [ X] There are no new spelling errors identified by the Manubot spellchecker

Spellcheck Step

The dictionary used for spellchecking can be updated.
Edit the file in build/assets/custom-dictionary.txt by adding new entries to the end.
You do not need to change anything else.
However, if you want to update the first line to have an accurate count of words and you want to remove non-unique ones, run the following command from within build/assets on your favorite OS X or Linux machine:

(( len = $(awk '!a[$0]++' < custom-dictionary.txt | wc -l ) - 1 )); tmpfile="$(mktemp)"; echo "personal_ws-1.1 en $len utf-8" > $tmpfile; tail -n +2 custom-dictionary.txt | awk '!a[$0]++' >> $tmpfile; mv $tmpfile custom-dictionary.txt

Hi @atlas4213 the author details look good, but you might have not been on the main branch when you created your branch, as I see some diffs here in the methods as well. Can you revert the methods file or pull the current methods file from main and put it in this branch so that there are no diffs? (or open a clean PR)
