A proposal stays on a white page in dark mode, like a document. Some of what sat on that page took dark mode's pale colours and almost disappeared: "Prepared for", package prices and table headings on the client's page, and "The client chooses", "Recommended" and "Description" in the editor. Everything on the page now keeps its light colours, and the editor's fields and buttons are light to match.
In line-item tables, such as a proposal's or an invoice's, a right-aligned heading now lines up with its field and no longer runs into the next heading ("QuantityUnit").
