 * The theme owns the page: its typeface, its colours, its width. What is set
 * here is the shape of a journal — the contents of an issue, the head of an
 * article, the blocks that fold away — and it is drawn in the theme's own
 * colour, tinted where a line or a background is needed. Nothing here names a
 * colour outright, so the plugin looks at home on a light theme and a dark one
 * alike.
