/* course-landing.css — TrainSkool course landing + instructor profile
 * Conversion-focused marketplace layout. Loaded AFTER styles.css so it can
 * override base element styling. Colours come from the shared design tokens
 * (:root / :root[data-theme="dark"]) so light + dark toggle "just work".
 * No inline styles: dynamic values arrive as CSS custom properties
 * (--course-accent, --w, --mono) set via el.style.setProperty in JS.
