/* Motion — a single IntersectionObserver in script.js watches the section
   and adds `is-visible` once; the quote block then plays its own slower,
   staged sequence (mark, then quote, then attribution), each on a longer
   `animation-delay` than the last. The `.about10--js` gate means the
   pending/hidden state below only applies once JavaScript has actually
   attached the observer — without JS every element sits at full opacity,
   so nothing here depends on JS to become visible. */
