/* ============================================================
   act2.css — "Act II": everything BELOW the scroll-film hero.
   The film is Act I. This makes the rest of the page feel like the
   same film continuing — declarative, data-attribute driven, and
   graceful under prefers-reduced-motion.

   Pairs with js/act2.js. The signature "tell" (grid substrate,
   captions grammar, wordmark, scroll ritual) lives in chrome.css and
   is NEVER touched here — this only adds the motion layer around it.

   Reduced-motion contract (critical): every initial-hidden state is
   wrapped in @media (prefers-reduced-motion: no-preference) AND gated
   on html.a2-js. So if motion is reduced, or JS/GSAP never loads, all
   content is fully visible and static — no invisible sections, ever.
