   B1.13 (finding 08): this sheet's entire content -- fourteen @keyframes
   plus .supernova-burst/.supernova-ring/.wave-bars/.wave-bar/.typing-indicator/
   .typing-dot/.stagger -- matched nothing in frontend-v2/js/*.js or index.html.
   The two keyframes that were referenced from elsewhere (fadeSlideUp from
   lesson.css, scaleIn from feed.css) turned out to only be used by rules that
   were themselves dead (.lesson__mode-content--active, .feed__modal, both part
   of abandoned BEM component trees deleted in the same pass). Nothing in the
   live app depends on this file; left in place (empty) rather than removed so
   index.html's <link> and sw.js's STATIC list don't need restructuring. */
