/* ---------------- Sticky navigation (the Hero's own nav, pinned) ----------------
   The Hero bakes its navigation into hero.jpeg across two cream bars: a top
   header strip (brand + "Get in touch") and a bottom strip (Projects /
   Offerings / About). To keep that navigation reachable on scroll WITHOUT
   redesigning, recreating or cropping the asset, we pin live slices of the
   very same image. Each `.strip` is a fixed-aspect window over hero.jpeg —
   the brand strip aligns the image to its top, the nav strip aligns it to its
   bottom — so what shows is exactly the approved artwork. The bar is parked
   off-screen and slides in only once the Hero's own nav has scrolled away,
   so navigation is never duplicated on screen. */
