/* ============================================================
   Scroll storytelling (homepage). The page is told in chapters:
   a pinned hero that steps back, pauses ("breaths") that stop the
   scroll for one thought, and a sea day told on a sticky stage.
   Motion lives in js/story-scroll.js (GSAP + ScrollTrigger).

   Without JS, or with reduced motion, everything below renders as
   a calm static page: pauses are full-height statements, the day
   falls back to the inline timeline from story.css.
