Style Guide for 'You Know Fulwell'

Some of my beta readers have requested a style guide outlining the choices I have made about the book's grammar, syntax, and spelling. If you, as a reader, find this whole list to be confusing, then feel free to ignore it and just give me notes on other things. Also don't hesitate to message me with any specific questions about usage, and I will update this document with any clarifications, corrections, or other new information.

British usage and spelling and usage should be maintained throughout ('rumour, not 'rumor'; 'complexion', not 'complection'; 'realise', not 'realize'; &c.). A full list appears at the end of this post.
