/* features.css -- the Features window (31 Oct 2026; features.js draws it, emby.js aboutSet opens it).
 *
 * Layout rhythm taken from moonfin.io (a hero with a stat strip, big feature groups with icons,
 * a "which screen are you on" picker, comparison tables, then a grid of smaller extras), because
 * a long list of features reads best broken into those blocks. Nothing else is taken from it:
 * no text, no logo, no artwork, no colours. Every colour here is one of the site's own tokens,
 * so the window follows the theme and the accent the visitor picked (the window's screen keeps
 * the dark palette in light mode, like Home, Timeline and About: index.html .about-pop).
 * All classes start with ft- so nothing here touches any other part of the page.
