/* =============================================================================
   AIO manifesto theatre — scroll-scrubbed chapters for section#about.
   Shared by / and /he/. Everything is gated behind html.premium-mf, which
   manifesto.js adds only on desktop (>=1024px), without reduced-motion, and
   while the a11y stop-motion toggle is off. Without the class the section
   renders exactly as before (label, quote, paragraph).
