/* adagia.study: a commonplace book in the app's own colours.
   Layout: one left-aligned reading column (66ch) with a wide right gutter for figures; sections separated by space, not boxes.
   Colour comes from the app: sage for practice, mauve for the library, slate teal for links, lamp amber, and Franklin's red ink in one figure only. */
