/*
 * documentation.css — the in-app / online product documentation reader.
 *
 * Hand-maintained. (It used to be compiled from stylus/documentation.styl;
 * that source has been retired.)
 *
 * Structure it styles (all ids/classes are emitted by the documentation
 * generator in lib/documentation.php, not hand-written):
 *     nav#sidebar           the table of contents; --sidebar-width wide, and the
 *                           page content is inset by that much when it is open
 *     div.search-overlay    the search results panel, below the toolbar
 *     .search-field         the search input inside the toolbar
 *     input#ctr_sidebar     hidden checkbox toggling the sidebar
 *     input#ctr_search      hidden checkbox toggling the search overlay
 *
 * Like the site's other controls, the sidebar and search panel are driven by
 * hidden checkboxes and their labels rather than by JavaScript, so they work
 * before od-manual.js loads.
 *
 * Theme values live in the custom properties on :root below. Custom properties
 * cannot be used inside media queries, so the two breakpoints are literal:
 *     768px   tablet: the root font size shrinks from 62.5% to 50%
 *     940px   = --max-content-width: below it the sidebar is hidden and
 *             toggled by its toolbar button; from 940px up it is always
 *             visible. The narrow-screen queries use max-width: 939.98px so
 *             that exactly one of the two layouts applies at 940px.
 *
 * Units: the root font size is 62.5%, so 1rem = 10px (8px below 768px).
 * Font sizes and the page layout (toolbar, sidebar, content column, gaps
 * between blocks, list and table indentation) use rem. Spacing that belongs
 * to a piece of text and should scale with it (heading padding, keys, inline
 * images, search highlight, controls in the toolbar) uses em, i.e. it is
 * relative to the element's own font size.
 *
 * Translucent variants of the theme colors are written as
 * color-mix(in srgb, <color> N%, transparent), which equals the color at N%
 * opacity. Lighter variants mix with white instead.
