/* ===========================================================================
   SolutionsChatops -- HERO: 2-column grid, secondary link, and the 4-scene
   "film" of the ChatOps window. Port of the
   SolutionsSales hero film pattern with this page's own names (.co-hero-*).
   State lives on .co-hero-film: [data-at="0..3"] = shown scene, [data-prev] =
   outgoing scene (keeps its end frame while it fades). .is-live = autoplay
   (solutions-chatops-hero.js, only when motion is allowed), .is-held = frozen
   (off-screen / tab hidden). EVERY rule outside .is-live is a final frame:
   no JS, reduced motion and paused all show still frames, scene 2 by default.
   Motion: transform / opacity only. Fixed stage heights: W 476 / N 470 /
   T 476 / P 496px, so switching scenes never moves the page.
   Never use .dc-ui-*, [data-go], [data-io], [data-count], [data-hot] or
   .dc-term here: the mockup JS looks those up document-wide.
