/* StockRepublic round-2 slides (agent T): chapter breaks, choice, idea, weeks. Scoped under .t2 and built only from the
   engine tokens in ../research-deck/styles.css. Entry motion uses backwards-filled animations, so the resting style is
   the final state: the engine's reduced-motion rule (animation:none) simply shows everything. Ambient loops pause
   with body.paused. */
