A book's public page showed light text on a white or light background to readers whose device is in dark mode. The page now keeps the background chosen in the book's settings, with its text, in both light and dark mode, and the background swatches in the settings show the same colours. In the reader's and the preview's Pages view, a chapter title was dark on the dark page in dark mode; it now takes the page's text colour.
Fixed books that could not be read in dark mode
A book's public page showed light text on its light background to readers in dark mode, and chapter titles disappeared in the Pages view. Both now read correctly.
