/* reader.css — the reader: reading themes, the bars, panels, popovers.
   The open-book look and theater mode are in theater.css.

   Reading themes are tokens like the app's: one block per theme, and nothing
   below writes a raw colour. The same blocks colour the theme chips in the Aa
   sheet and in Settings (via data-rd-theme), and reader/styles.js reads them
   to colour the text inside the book.                                        */
