/*
 * Custom responsive sidebar (hand-rolled instead of Bootstrap's offcanvas-lg
 * component, which requires Bootstrap 5.2+ — this project intentionally
 * keeps the shared /css/bootstrap.min.css at 5.0.0 to match the original
 * public-site template, so offcanvas-lg has no effect and the sidebar would
 * otherwise render permanently shifted off-screen while still reserving its
 * layout width). Toggled via a small script in layout-foot.php.
