   CSO RECRUITMENT — pinned stage, scroll-triggered card spread

   Same track+sticky pattern as ABOUT (see .about-scroll-track): a tall
   track spends scroll distance while .cso-sticky-stage stays pinned.
   Five cards start gathered near center; js/cso-scroll.js
   fires a single ~500ms transform transition to fan them out (or gather
   them back) the moment it sees a scroll in that direction — position is
   not tied to scroll distance. See js/cso-scroll.js for the state
   machine. The inner surface owns the design; the wrapper owns motion.

   WHY MEDIONE / PARTNER SUPPORT — pinned step story

   Same track+sticky pattern as about-scroll.js/cso-scroll.js: a tall track
   spends scroll distance while .partner-story-sticky stays pinned. The
   right-hand nav cards sit in fixed slots — only which one carries
   .is-active changes — and the left main card crossfades its visual/text
   in place (see js/partner-story.js) instead of being torn down.
