From https://docs.citationstyles.org/en/stable/specification.html#text-case:

“sentence”: renders text in sentence case (deprecated; do not use)

I think "capitalize-first" should be enough, but you actually supposed to store sentence case values yourself:

CSL processors don’t recognize proper nouns. As a result, strings in sentence case can be accurately converted to title case, but not vice versa. For this reason, it is generally preferable to store strings such as titles in sentence case, and only use text-case if a style desires another case.

But I don't see any reason to use sentence case in the first place, hence why I updated all occurrences of text-case="sentence".

Additionally, I'm confused as to why terms "edition", "volume", and "page" are used, but not defined. For the "page" I assume C. is used, but for volume...yeah it could translate to different things. Moreover, in the standard itself not always a capital letter is used for volume, which could be a typo, though also could mean that the uppercase is not mandatory, therefore the text-case part for "volume" can be dropped. But the majority of examples uses uppercase, so it's probably fine.
