/* guide.css — public /guide page (templates/guide.html).
 *
 * Loads AFTER styles.css (brand tokens + .btn/.card) and landing.css
 * (lp-nav / lp-footer / section primitives). This file adds only the guide's
 * own layout: a sticky table of contents beside a prose column. All classes
 * are .gd- prefixed; anchors get scroll-margin + a :target flash so arriving
 * from a landing tile or an in-app "learn more" link visibly lands somewhere.
