This sells Zotero short in so many ways, but you do you, I guess. Have fun hand formatting between the dozen citation/reference formats every other journal chooses, seemingly at random
Why would you need that? 99% of the time, you'll just grab the BibTeX from where you're getting the paper (Google Scholar, arXiv, ResearchGate, etc.) and paste it on the .bib file. LaTeX will take care of formatting it when you \cite.
I was wrong. I was not aware that biblatex had these features so easily available. Learned something.
Isn't citation format handled entirely in the latex document itself?
Mostly yes, you still need to check capitalisation of special words... But this should be independent of the actual citation style.
