/* MagpieFeed homepage, v4 showcase sections: How it works (sticky rail), the owners bento
   with its network marquee, and the examples tabs. Loaded AFTER landing.css, so the rules
   here win at equal specificity. Colours are tokens only (static/css/tokens.css), so the
   dark scheme follows. Motion: CSS + static/js/landing-showcase.js, 160-220ms, one easing,
   and all of it sits behind prefers-reduced-motion: no-preference or a JS-set class, so
   without script or with reduced motion the page is complete and static. */
