/* ==========================================================================
   Intro reel: "I lead teams. I still design."
   A 31-second product-design intro that covers the hero, then becomes it: its last frame is the
   homepage hero, and the dark stage dissolves into the page. Editorial and restrained: the site's
   type, a 12-column grid, interface fragments drawn as simple blocks, orange only for key words,
   numbers and the human decision points. Sizes use container units (cqw/cqh) of .intro__frame.
