/**
 * Styling for textbook pages. Jupyter notebooks generate their own HTML markup
 * which we style under the #ipython-notebook selector.
 *
 * Most of the textbook content is styled using this component.
 *
 * [1]: Within-textbook__page layout
 * [2]: Since we use JS to focus the page on load, hide the outline to avoid
 *   visual cruft.
 *
 * Notebook styling:
 *
 * [4]: Some tables are too wide for the page on smaller screens so we let the
 *   user scroll horizontally.
 * [5]: Inline code snippets (usually variable names) should have a gray bg.
