/* Landing-page widening.
 *
 * The index page hides its secondary (right-hand) sidebar via the
 * ``:html_theme.sidebar_secondary.remove:`` file directive, but the article
 * column still keeps its narrow 60em reading width.  These rules let the
 * article expand into the freed space, but only on pages that include the
 * ``attnax-landing`` marker div (emitted by index.rst via ``raw:: html``).
 * Other pages keep the comfortable reading width.
 *
 * The selectors mirror the theme's compound selectors (e.g.
 * ``.bd-content .bd-article-container``) so specificity matches, and the
 * overrides are marked ``!important`` because the same trick is needed by
 * JAX and other large book-theme sites.
