/* Scrolling text band — views/sections/marquee.php. Full bleed: one line of texts with small dots between
   them, looping by sliding the track (the list twice, each copy at least a screen wide) by half its width.
   Background and text colour come from the section wrapper. The pointer over the texts, keyboard focus and
   the pause button (revealed by marquee.js, .is-ready) stop it; off-screen bands rest (.is-offscreen).
   Reduced motion: no animation and no button, the texts stand centred and wrap onto more lines. */
