/* Clickable scene tabs (radio group, no JS). Each tab has two radios (…1 / …2) and shows the label for
   whichever one is NOT checked, so every click checks a different radio. Each radio swaps in its own
   copy of the keyframes, which restarts the 21s cycle offset to begin at the clicked scene; rotation
   then carries on through the next scenes and loops forever. Tab highlight runs on the same timing. */
