/* ==========================================================================
   Capabilities + Recognition
   A sticky intro column paired with a normally-scrolling list of capability
   cards, followed by an awards strip and two supporting photos.

   The sticky column uses native CSS `position: sticky` — never a GSAP
   `pin` — so it can't desync from the site's Lenis smooth scroll (same
   reasoning as the Honest Experiences testimonial stack). Because the
   right column (.ai-dev-cap-track) is taller than the left column's sticky
   content, the browser keeps the left column fixed for exactly as long as
   the right column has more cards to show, then un-sticks it automatically
   once `.ai-dev-cap-inner` runs out of height — no bespoke "release" logic
   needed, and no risk of the two ever falling out of sync. GSAP
   ScrollTrigger is layered on top only for the card entrance reveal
   (sitewide `.scroll-reveal-item` system, see main.js) and the "active
   card" highlight (see ai-development-services.js) — neither of which
   touches layout/positioning.
